Stacked Area Chart
This stacked area chart visualizes the global market share of popular web browsers from June to September 2015, using data from Clicky Web Analytics. Time-series data for eight browser categories is loaded from a TSV file and stacked using `d3.stack`. The visualization encodes dates on the x-axis with `d3.scaleTime`, market share percentages on the y-axis with `d3.scaleLinear`, and browser categories with the ordinal color scheme `d3.schemeCategory10`. Regions are drawn as SVG paths via `d3.area`, with axes generated by `d3.axisBottom` and `d3.axisLeft`.
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
