Multi-Series Line Chart - 1
Daily average temperatures for New York, San Francisco, and Austin over one year are plotted as three colored lines in a multi-series line chart. The visualization uses the D3.js library, specifically `d3.tsv` to load and parse the data, `d3.scaleTime` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.schemeCategory10` for color encoding. SVG paths render each city’s line, with axes and labels drawn using `d3.axisBottom` and `d3.axisRight`. The y-axis is labeled in degrees Fahrenheit.
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
