This example visualizes daily temperature readings for three cities—New York, San Francisco, and Austin—as a multi-series line chart over an October timeframe. The data is embedded directly in the source as a tab-separated string parsed with `d3.tsv.parse`. Using D3 v3 SVG rendering, it employs `d3.time.scale`, `d3.scale.linear`, and `d3.svg.line` with basis interpolation to draw smooth temporal trends. A categorical color scale distinguishes each city, and the chart includes axes, a legend, and city labels positioned at the final data point.
