{"version":"1.0","type":"rich","title":"Multiple lines","description":"This example visualizes a week of temperature readings from multiple cities using multiple colored lines, with a legend identifying each city. The chart uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` for axes, `nest()` to group data by city, and `line()` with `curveBasis` for smooth paths. A categorical color scale assigns distinct strokes, and a custom `colorLegend` function renders the legend. Data is loaded from a CSV file via `d3.csv`, with axes from `axisBottom` and `axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/840ad04506394e329a3b170f526954a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
