Multi-Series Line Chart
This multi-series line chart displays daily average temperatures for New York, San Francisco, and Austin over one year, loaded from a TSV file and rendered as an SVG. The x-axis encodes dates using a time scale, while the y-axis uses a linear scale for temperature values, with the domain computed via d3.extent, d3.min, and d3.max. A categorical color scale (category10) distinguishes the three cities, and each series is drawn as a smooth line using d3.svg.line. The chart includes conventional margins, axes generated with d3.svg.axis, and data parsed from the TSV with d3.tsv and d3.time.format.
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
