{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example uses the Vega-Lite API to render a bar chart from CSV data, with a custom dark theme applied through configuration. The visualization is built declaratively in `viz.js` using `vl.markBar()`, mapping fields `a` and `b` to the x and y axes, while `index.js` orchestrates the data loading via D3’s `csv` function and registers Vega-Lite with tooltip support. The chart is sized to fill the viewport using the `autosize` directive, with axis and label styling customized in `config.js` for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad59814194884b9b8ecc2834feabe1d3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
