{"version":"1.0","type":"rich","title":"Harvard/MitX Video Views","description":"This visualization shows the number of video view events for courses from HarvardX and MITX during the 2013 academic year. It uses a bar chart with courses sorted descending by view count and color-encodes whether the course was certified. The visualization is built using the vega-lite-api library on top of vega-lite and vega, with data loaded from a TSV file via d3.tsv. The appearance is customized through a configuration object that adjusts axis colors and font sizes for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48d88127dcc74957b0b6b9034a748bea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
