Multi-Series Line Chart
This multi-series line chart visualizes daily average temperatures in New York, San Francisco, and Austin over one year, loaded from a TSV file using d3.tsv. The x-axis uses a time scale to encode dates, while the y-axis uses a linear scale for temperature values. Each city’s temperature series is drawn as a distinct colored line using an ordinal color scale (category10). The chart applies conventional margins, computes domains with d3.extent, d3.min, and d3.max, derives series names via d3.keys, and renders axes and lines using SVG.
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
