{"version":"1.0","type":"rich","title":"EdX Viewer Data by Course and Country, AY2013","description":"This stacked bar chart shows the total number of EdX video views for each country during AY2013, with each bar segment color-coded by course. The visualization uses the vega-lite-api to build a bar mark with an aggregate sum of `nplay_video` on the y-axis and country on the x-axis, sorted by total views. A sinebow color scheme distinguishes courses, and tooltips display the aggregated view counts per segment. Data is loaded from a CSV file hosted on GitHub, originally sourced from the MITx-HarvardX Dataverse, with custom axis and label styling via vega-lite configuration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22a2dab4a7dd4c7cb0f529875a84b442?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
