{"version":"1.0","type":"rich","title":"Multi-line chart","description":"A multi-line chart displays a week of worldwide temperature readings per city, with each city’s time series drawn as a smooth basis curve. The visualization uses React to render SVG elements, while D3 v5 handles scales, axes, and the `d3.nest()` grouping of data by city. Animated color legend circles appear via a custom `colourLegend` component, and the chart applies a categorical color scale with semi-transparent paths for overlapping lines. Temperature data is loaded from a remote CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/194ceb581fe54a958db26a4a4b00262f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
