{"version":"1.0","type":"rich","title":"line chart ordinal data","description":"This line chart maps ordinal letter categories (a–m) from a CSV file to their corresponding numeric values. The visualization uses D3 v5’s `scalePoint` for the x-axis and `scaleLinear` for the y-axis, rendering a smooth curve via `line()` with `curveBasis`. Circles mark each data point, while axes are generated with `axisBottom` and `axisLeft`. The SVG output includes a black stroked path and teal circular markers, with data loaded asynchronously through `csv()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2de9d780e4de44a0b20de3ebbfc291cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
