Parerga und Paralipomena » Blog Archive » Messing around wih D3.js and hierarchical data These days there are a lot of browser-oriented visualization toolkits, such d3.js or jit.js. They’re great and easy to use, but how much do they scale when used with medium-large or very large datasets? The subject ontology is a quite large (~2500 entities) taxonomical classification developed at Nature Publishing Group in order to classify scientific publications. The taxonomy is publicly available on data.nature.com, and is being encoded using the SKOS RDF vocabulary. In order to evaluate the scalability of various javascript tree visualizations I extracted a JSON version of the subject taxonomy and tried to render it on a webpage, using out-of-the-box some of the viz approaches made available; here are the results (ps: I added the option of selecting how many levels of the tree can be visualized, just to get an idea of when a viz breaks).

Method: Data visualization with D3.js and python - part 1 - Next Genetics View the demo hereHTML source is at the bottom of the post Computers and the internet have changed academia in dramatic ways from greater sharing of data to a larger sense of community. Science journals are now all digitized and available online either through your web browser or downloadble as a .pdf. Even with all the technology available for presenting data, most published papers still only contain static figures.

3 Representational Models That Affect Usability A few weeks ago while talking about visual perception and memory, I mentioned how the mental models your audience hold affect how they perceive your designs. Today I want to expand on the topic and consider the conceptual model of the designer as well as the interaction model or where designer and audience meet. Before getting to the details let’s quickly define each of the 3 models. Mental model— how users think a system will workConceptual model—how designers develop a system to workInteraction model—how people actually interact with a system Mental Models A mental model represents a persons thought process for how something works.

Visual Index Scatterplot Scatterplot This scatterplot is constructed from a TSV file storing the dimensions of sepals and petals of various iris flowers.

Threejs Britzpetermann was commissioned to create an installation for the entrance hall that draws attention to the topic energy. The team decided to break down the topic energy and chose the 4 elements, the basis of all energy extractions which are used in the park and present in an elegant and interactive way. Driven by the idea of a droplet of water following a line, Manny Tan created this Three.Js experiment that explores a droplet shape and it’s associated views in 3d space. The web application allows you to click and drag to rotate the shape. Alternatively, you can use the scroll wheel or right click and drag to move […]

50 Great Examples of Data Visualization Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information. And trying to find related content can also be difficult, depending on what data you’re looking for. But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner. Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter.
