This stacked area chart is constructed from a TSV file storing the market share of several popular web browsers over the last year. Data is from [Clicky Web Analytics](http://getclicky.com/marketshare/global/web-browsers/). The chart employs [conventional margins](http://bl.ocks.org/3019563) and a number of D3 features:

* [d3.tsv](https://github.com/d3/d3-request#tsv) - load and parse data
* [d3.timeFormat](https://github.com/d3/d3-time-format#timeFormat) - parse dates
* [d3.format](https://github.com/d3/d3-format#format) - format percentages
* [d3.scaleTime](https://github.com/d3/d3-scale#scaleTime) - *x*-position encoding
* [d3.scaleLinear](https://github.com/d3/d3-scale#scaleLinear) - *y*-position encoding
* [d3.scaleOrdinal](https://github.com/d3/d3-scale#scaleOrdinal), [d3.schemeCategory20](https://github.com/d3/d3-scale#schemeCategory20) - color encoding
* [d3.extent](https://github.com/d3/d3-array#extent) - compute domains
* [d3.stack](https://github.com/d3/d3-shape#stack) - compute stacked *y*-positions
* [d3.axisBottom](https://github.com/d3/d3-axis#axisBottom), [d3.axisLeft](https://github.com/d3/d3-axis#axisLeft) - display axes
* [d3.area](https://github.com/d3/d3-shape#area) - display area shape
