{"version":"1.0","type":"rich","title":"EdX Video Views by Country, AY2013","description":"This stacked bar chart shows total EdX video views by country for the 2013 academic year, with color encoding distinguishing countries. The visualization uses the vega-lite-api to construct the chart, with `vl.markBar`, `vl.y().fieldQ('TotalViews')`, and `vl.x().fieldN('Countries').sort('y')` specifying bar marks and quantitative/ordinal encodings. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV originating from the MITx-HarvardX Dataverse. The chart is rendered with Vega, Vega-Lite, and Vega- Tooltip, customized through a config file that adjusts axis styles and label formatting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d5ed8e378964f3d869f2233aa8fdcf2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
