{"version":"1.0","type":"rich","title":"D3 Line Chart with Multiple Lines","description":"This example displays temperature readings from multiple cities over time as smoothed, multi-hued lines, with a color legend identifying each city. It uses the D3 v5 library, building the chart with SVG and relying on `scaleTime`, `scaleLinear`, and `scaleOrdinal` to map data. Data is loaded from a CSV file, and lines are generated using `line` with `curveBasis`, while axes use `axisBottom` and `axisLeft`. The visualization also employs a custom `colorLegend` function to render the categorical color key.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1962a5c8d5345f18096cd9834c25414?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
