Multi-Series Line Chart
This multi-series line chart shows daily average temperatures for New York, San Francisco, and Austin over a year, with each city’s trend drawn as a colored, animated line. The data is loaded from a TSV file, and the chart includes interactive click-to-hide and hover-to-highlight features. It uses d3.tsv for parsing, d3.scaleTime and d3.scaleLinear for axes, d3.scaleOrdinal with d3.schemeCategory10 for colors, and d3.line with d3.curveBasis for the lines.
