Stacked Area Chart
This stacked area chart shows the daily market share of web browsers over a three-month period, with each browser represented by a colored area stacked to total 100%. The visualization uses D3 v4 to load TSV data from Clicky Web Analytics, parse dates with `d3.timeParse`, compute stacked y-positions with `d3.stack()`, and render areas using `d3.area()`. Axes are drawn with `d3.axisBottom` and `d3.axisLeft`, while colors come from `d3.schemeCategory10` via `d3.scaleOrdinal`. The final SVG output includes labels for each browser placed at the right edge of the chart.
AI-generated descriptionThis 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. The chart employs conventional margins and a number of D3 features:
- d3.tsv - load and parse data
- d3.timeFormat - parse dates
- d3.format - format percentages
- d3.scaleTime - x-position encoding
- d3.scaleLinear - y-position encoding
- d3.scaleOrdinal, d3.schemeCategory20 - color encoding
- d3.extent - compute domains
- d3.stack - compute stacked y-positions
- d3.axisBottom, d3.axisLeft - display axes
- d3.area - display area shape
