Multi-Series Line Chart
This multi-series line chart displays daily average temperatures for New York, San Francisco, and Austin over one year, using color to distinguish each city's trend. The visualization encodes dates on the x-axis via `d3.time.scale` and temperatures on the y-axis via `d3.scale.linear`, with `d3.svg.axis` rendering the axes. Data is loaded from a TSV file using `d3.tsv`, and each city’s line is drawn with `d3.svg.line`, colored by `d3.scale.category10`. The chart uses conventional margins and an SVG rendering approach, with city labels placed at the final data point.
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
