Multi-Series Line Chart
This multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over the course of a year, with each city encoded as a colored line. The x-axis represents time using d3.time.scale, while the y-axis uses a linear scale for temperature values. Colors are assigned via d3.scale.category10, and the data is loaded from a TSV file using d3.tsv. The chart applies conventional margins, computes domains with d3.extent, d3.min, and d3.max, and renders axes and lines using d3.svg.axis and d3.svg.line. The visualization compares seasonal temperature patterns across the three cities, highlighting relative warmth and variation throughout the year.
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
