This interactive visualization displays bike ride data as an arc diagram, with each arc representing a ride type. Users can filter the data by year and membership type using dropdown menus, which updates the visualization dynamically. The chart is built using Vega-Lite API within a React framework, with Vega and Vega-Lite handling the rendering. Data is loaded from a CSV file using D3’s `csv` function, and the visualization computes quantitative theta values from the ride type field, encoding color by the same nominal attribute.
