Released versions of OneZoom span from 1.0 (2012) to 3.4 (2020). Some features from earlier versions have not been retained in the latest software, so versions 1.0 and 1.2 remain available to provide access to these features - such as customisation of the view to accommodate a user's tree and the growth animation function for dated trees.
Using source code from our public GitHub repository
All our live source code is available to view on our public GitHub repository. Some parts are available for reuse under OSI approved fully open source licenses. All other parts can be freely reused under a OneZoom non-profit source available license. This basically means they are free to use for the advancement of science and science education, but not for commercial purposes. We know that 'commercial' can be an elastic term, we are willing to interpret this in a relaxed way to support any project whose aims are consistent with our own mission statement. If you think this applies to you, please write to us and we'd be happy to consider providing you with a letter confirming that we don't consider your project to be commercial. For further details please see our plain language license FAQs.
Our objective is to encourage broad reuse of the OneZoom code whilst also protecting our unique model for maintaining the codebase and sustaining the live website. If the OneZoom organisation ceases to exist our software will automatically become available under an OSI approved MIT license. Remember that OneZoom is a registered not for profit organisation and the majority of work is done by unpaid volunteers. If you have suitable software development expertise and want to contribute please let us know, we'd be delighted to work with you.
Hosting your own variation of the OneZoom complete tree of life explorer.
If you contact us we can provide help and add you to our developer community from which you can receive support. The keys steps to getting started are as follows...
- Read the license, plain language license FAQs and readme documentation, ask us about any queries or concerns.
- Pull the latest version of OneZoom from our public GitHub repository and follow the instructions in the readme file.
- Contact us for a database dump (which will include everything we have except for sponsorship information). Alternatively run our Python scripts to generate your own data, but this will be harder and involves many steps includin getting large source data dumps from Open Tree of Life and Wikipedia as well as intensive use of the IUCN and EOL APIs to aquire further data.
- Optional: get copies of the images from us so they can be hosted in an environment disconnected from the internet, such as a touch table without a network connection.
Includes all the features of version 3.3.1 and adds a completely redesigned landing page together with improvements to the site content as a whole.
Version 3.3.1 (obsolete)
Includes all the features of version 3.3 and adds code to build a museum tree of life display exhibit in seconds. In particular, i) the user interface has been customized for museum display use, ii) the display URL has been 'sandboxed' so that users can't break out and explore material outside the tree of life and taxa pages on Wikipedia, iii) a new tutorial has been added to the display, and iv) a 'screensaver' function ensures that unattended displays automatically reset and fly around the tree to attract potential users passing by. A new launch page enables customization of the museum display including the home taxa location, language, view type and other settings. Version 3.4 also features some updates to the menus and pages on the website outside of the tree of life explorer.
Version 3.3 (obsolete)
Includes all the features of version 3.2 and adds a polytomy view, performance enhancements, changes to the way images are processed to enable compatability with the latest version of the Encyclopedia of Life, and specific developments to support the One Tree, One Planet tree view.
Version 3.2 (obsolete)
Includes all the features of version 3.1 and adds enhanced multi-language support, a new user interface for the tree explorer and a documented framework enabling others to easily design a complete OneZoom tree into their website or public display without needing to touch the core software.
Version 3.1 (obsolete)
Includes all the features of version 3.0 and adds substantial performance enhancements as well as basic multi-language support. Behind the scenes the core visualisation software has been entirely refactored and modularised in ECMAScript 6.
Version 3.0 (obsolete)
Includes all the features of version 2.0 and adds dynamic loading and caching systems so that the entire tree of life can at last be viewed on a single page. A common ancestor search function was also added as well as a URL parser that stores your position in the tree.
Version 2.0 (obsolete)
A more advanced website incorporating a tree that spans the whole of life, semi-automated systems to keep the tree up to date, the ability to sponsor a leaf on the tree, improved visual design, and an enhanced user interface. This version incorporates mobile and touch screen support as well as embedded images from version 1.2 kiosk.
Some features were lost from version 1.2 variants: there is no longer an animal sound player, growth animation, kiosk version, customisable html embed function, or feature to load your own phylogeny. Version 1.2 still runs within version 2.0 to provide lecacy support of these features.
The most advanced OneZoom website that can be hosted simply by copying the files into your webspace. More recent versions of OneZoom from 2.0 onwards require running your own Python based webserver and SQL database server.
All downloads of OneZoom version 1.2 are released under an MIT license which is OSI approved. Please note that the zip files also contain Boot Strap and jQuery which are built by third parties and licensed for further use under those third party license rules (please open the source files for information). The zip files may also include icons for e.g. facebook and twitter which are should be used under the terms of those organisations but are provided here for convenience.Download OneZoom 1.2, this is the complete OneZoom website fully functional as it was live online until April 2016 when version 2.0 was released.
Embed a customised OneZoom tree in your website using version 1.2.
Without downloading or installing any software you can still use our embed and link tool if you want to embed custom versions of a tree that's already on OneZoom. After selecting the settings you want the page will generate a short piece of code that you can copy any paste into your website to give you a OneZoom visualisation. This can incorporate highlights of pairs of taxa and their common ancestors as well as zooming animations and user interaction. If you want to use your own tree data, however, you will need to download the code and edit the data sources.
Version 1.2 lite
A cut down version 1.2 designed to be easier to edit and use to build your customised explorable tree pages. Download OneZoom 1.2 lite
Making supplementary material for your papers using version 1.2 liteIf you've got a big and impressive tree and are interested in having it appear on OneZoom we can work with you on this, and we can time the date your page goes live with the embargo period of your associated journal publication.
- Download and uncompress the cut down version of the 2015 website.
- You should only need to edit the files in the user directory - there are two examples here, one for tetrapods and the other for plants.
- Each example data set contains a Newick tree file (no polytomies) and a metadata file which is indexed by numbers that must correspond to the leaves of the tree file.
Version 1.2 kiosk
This is very different from the other version 1.2 varients in terms of functionality. This code provides an easy to deploy explorer for touch screen environments in public venues. It has been developed using feedback from surveys and observations made at venues hosting the display. Features include... embedded images, embedded animal sounds, dynamic zooming around the tree when not in use, full search functionality and a bespoke on screen keyboard so that the system keyboard need not be exposed to users.
Download OneZoom version 1.2 kiosk , note that to function properly this also requires raw data that is not included in the download. You will need to unzip the software, then contact us to request an example data set (we have tetrapods and plants). You can then use this to learn the file formats and layouts necessary to input your own data without needing to edit the code itself.
The first version of OneZoom with basic features released alongside a publication in PLoS Biology. This version of OneZoom will still be useful if you want to quickly explore a Newick formatted phylogeny online. It also has the advantage of comprising of a single easily portable file which includes all code and data, later versions of OneZoom all use complex directory structures containing a range of files. Download OneZoom verion 1.0 licensed under an MIT license which is OSI approved.
View your own data online using version 1.0
Note that your data is only stored on your personal computer for this visualisation and is not transmitted over the internet so it is safe to visualise unpublished data in this way. If you prefer, you can still download OneZoom version 1.0 and do everyting locally and offline.
- First, load the original single stand alone file version of OneZoom in a new window. This code is a slightly updated version of the supplementary material to the article in PLoS Biology. The code is also available for download as a zip in the downloads section of this page.
- The mammal data will load by default. On the top of the page there is a row of buttons: Search, Grow, Options, Data, Reset, ... You need to press the "Data" button.
- A text box will appear at the bottom of the page, next to this is a button titled "Load data".
- Your data should be in Newick format with no polytomies (polytomies should be expessed with a number of nodes connected with branch lengths of 0). Branch lengths, if present, should be ultrametric and calibrated with units of millions of years.
- Only load one tree at a time and make sure there is no other text either side of the Newick code for that tree. Copy and paste the Newick format data for your tree into the text field at the bottom of the page and press the "Load data" button. Don't worry if your computer doesn't seem to have put all the data into the text box. Not all browsers are used to having very long strings of data in the text box, but the data is normally still there and loading will still work.
- Be patient, if your tree has 50,000 nodes or more it can take a minute or so to load and may use a noticeable chunk of ram on your computer. Most computers should be able to handle tress with 1 million nodes or more if you are willing to wait for it to load.
Use of OneZoom and the Interactive Fractal Inspired Graph (IFIG™) concept for other types of big data visualisation. Possibilities that we are evaluating include ...
- Monitoring of large and complex industrial processes
- Global financial data
- Spending and performance data
- Directory structures
- Complex computing structures including hardware and software
- Exploration of the contents of personal computing devices
- Databases of drugs for healthcare
- Exploration of the products available for purchase from large online stores
- Family trees, genealogy and pedigrees
- We'd like to see a OneZoom visualisation of the Google Knowledge Graph. This could be done by allowing the same data to appear in multiple places as part of an infinitely zoomable tree of knowledge assocation from any given starting topic.
