Multi-Series Line Chart interact
This interactive multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over one year. It uses D3 v4 to load a TSV dataset, parse dates with d3.time.format, and encode time on the x-axis with a time scale and temperature on the y-axis with a linear scale. A categorical color scale distinguishes the three cities, each rendered as an SVG line path. The chart applies conventional margins, computes domains using d3.extent and d3.min/max, and displays axes with d3.svg.axis. Hovering over the chart animates the lines, highlighting the nearest city's temperature values for interactive exploration.
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
