{"version":"1.0","type":"rich","title":"Harvard/MitX Video Views","description":"This chart aggregates total video views per course from a Harvard/MITx person-course dataset, using color to encode engagement categories and sorting courses by descending view counts. Built with the vega-lite-api, it declares a bar mark with quantitative x-axis sums and categorical y-axis fields, then renders through Vega-Lite’s SVG renderer. The visualization loads data via d3.tsv and applies custom axis styling from a config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c80a6f3c9d24c7f9cf2fb56930b55ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
