Multi-Series Line Chart
This visualization displays the daily average temperature for New York, San Francisco, and Austin over a year, with three colored lines allowing direct comparison of seasonal patterns. The chart uses D3 v3 APIs, including `d3.tsv` for data loading, `d3.time.format` for date parsing, `d3.time.scale` for the x-axis, `d3.scale.linear` for the y-axis, and `d3.scale.category10` for color encoding. It renders with SVG, using `d3.svg.axis`, `d3.svg.line`, and `d3.keys` to structure city series from the TSV data.
AI-generated descriptionThis line chart is constructed from a TSV file storing the daily average temperatures of New York, San Francisco and Austin over the last year. The chart employs conventional margins and a number of D3 features:
- d3.tsv - load and parse data
- d3.time.format - parse dates
- d3.time.scale - x-position encoding
- d3.scale.linear - y-position encoding
- d3.scale.category10, a d3.scale.ordinal - color encoding
- d3.extent, d3.min and d3.max - compute domains
- d3.keys - compute column names
- d3.svg.axis - display axes
- d3.svg.line - display line shape
