Multi-Series Line Chart
This multi-series line chart shows daily average temperatures for New York, San Francisco, and Austin over a one-year period. The D3 visualization loads data from a TSV file, parses dates with `d3.time.format`, and encodes time on the x-axis using `d3.time.scale`, temperature on the y-axis via `d3.scale.linear`, and city categories with `d3.scale.category10`. The chart displays axes using `d3.svg.axis` and renders each city’s temperature trend as a smooth line via `d3.svg.line` with basis interpolation. SVG is the rendering target, and city labels are placed at the final data point of each series.
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
