{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays a week of temperature readings from multiple cities, with each city represented by a colored, smoothed line. The visualization uses D3 v5's `nest()` to group data by city and `scaleTime`/`scaleLinear` for axes. A custom `colorLegend` component renders the categorical color scale, while `axisBottom` and `axisLeft` include gridlines. Data comes from a CSV file loaded via `csv()`, and the SVG rendering applies a multiply blend mode to overlapping lines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fce78a0048fc4712a87d526035f0e5f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
