It uses a stacked bar chart with a sinebow color scheme, where each bar segment represents a distinct course. The Vega-Lite API, built on D3, renders the chart in SVG, with axis and label styling customized in a separate config file. Data is loaded asynchronously via D3’s `csv` method from a GitHub-hosted dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74daf58b6ef445da88581d6babafb912?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
