Spoiler: The graph starts moving much more quickly towards heavier players in the 80s when growth hormones and steroids started getting serious, while the average height goes up at a pretty steady rate the whole time. That’s… depressingly unsurprising.
Really slick timeline visualization that can pull in data from a Google Spreadsheet, Flickr, etc. I plan on using this for some weird stuff.
D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. As a trivial example, you can use D3 to generate a basic HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction.
… then you should be pretty excited about d3 right about now. Even if you don’t grok the language, the examples speak for themselves.
