Harvard/MitX Engagement
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.
