This example visualizes a workshop’s conference registration data, showing the distribution of attendees by their school affiliation and year of study. The visualization uses D3 v4 to render SVG circles, with each data point representing an individual order. The code leverages `d3.select` to bind the embedded dataset and positions circles based on categorical groupings, while animation via D3’s transition methods highlights the points upon load. The raw data, including order timestamps and area codes, is hardcoded in the script, and the rendering focuses on the static SVG container.
