Multi-Series Line Chart
This multi-series line chart shows the daily average temperatures in New York, San Francisco, and Austin over one year, with each city’s values plotted as a separate colored line and labeled with its name. The data is loaded from a TSV file using `d3.tsv`, parsed with `d3.timeParse`, and encoded with `d3.scaleTime`, `d3.scaleLinear`, and `d3.scaleOrdinal` using `d3.schemeCategory10`. Lines are drawn with `d3.line`, while axes are rendered via `d3.axisBottom` and `d3.axisRight`, and the SVG also includes small circles for each data point plus text annotations showing the temperature extremes.
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
