{"version":"1.0","type":"rich","title":"Harvard/MitX Engagement","description":"A pie chart visualizes engagement by counting video view events per HarvardX/MITX course from the 2013 academic year. The chart encodes course ID on the y-axis and view counts on the x-axis, with color mapping to engagement categories and tooltips showing course identifiers. Built with the vega-lite-api library on d3.v5, it loads tabular data from a CSV file hosted on GitHub, with appearance adjusted via a custom config object for axis and label styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e667bae4342448e86e2306ec9402bf3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
