The latest thing I made at work is a timeline of press mentions of the people we have in our database. Behind the scene, we do some data mining on renown blogs, papers and magazines to find mentions of executives and staff. The idea was to have a detailed view of these press mentions (the timeline below, which will show you gaps if the person wasn’t mentioned for a while), and a global view of the mentions on the chart, so you can see the spikes. You can over on each cube to see an excerpt of the article and click to read it.
All of what you see is made with d3 (chart and timeline). The chart is in SVG and the timeline is simple HTML.
