Multi-Series Line Chart
This multi-series line chart displays daily average temperatures for New York, San Francisco, and Austin over a year, with each city’s trend encoded by color and labeled at the line’s end. The visualization uses D3 v4 to load data from a TSV file, parse dates with `d3.timeParse`, and scale both time and temperature via `d3.scaleTime` and `d3.scaleLinear`. Ordinal colors come from `d3.scaleOrdinal` with `d3.schemeCategory10`, while paths are drawn using `d3.line` with a basis curve, and axes are rendered through `d3.axisBottom` and `d3.axisLeft`.
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
