Introductions & Core Concepts Specific Techniques Blogs 38 Tools For Beautiful Data Visualisations As we enter the Big Data era, it becomes more important to properly expand our capacity to process information for analysis and communication purposes. In a business context, this is evident as good visualisation techniques can support statistical treatment of data, or even become an analysis technique. But also, can be used as a communication tool to report insights that inform decisions.
HeliosJS by entrendipity HeliosJS is an in-memory graph database for modern browsers. It employs a non-blocking asynchronous architecture through the use of Promises and Web Workers, and therefore is only available in browsers that support Web Workers. This enables HeliosJS to download and process large data sets without blocking the UI. In order to traverse the graph, HeliosJS uses a Gremlin inspired graph traversal language to query, analyze and manipulate the graph.
April 2012 Now as promised, here is some example code that builds on top of the d3 examples. I will start with the 'Force directed layour (with labels & images)', then add a coloured circle on each node and as well add some code to bound the nodes and links to within the SVG canvas, taking inspiration from another example 'Bounded force layout'. Let's walk through the code. First, the headers including the latest d3.js files, and some CSS: Create the SVG canvas and attach it to the tag declare above.
Let’s Make a Bar Chart, III In the previous parts of this tutorial we made a basic bar chart in HTML and then in SVG; now, we’ll improve the display by rotating the chart into columns and adding axes. We’ll also switch to a real dataset, showing the relative frequency of letters in the English language.

The library occupies a global variable of Chart.
