A scatterplot shows the relationship between the average rating and average complexity of the top 250 board games from a BoardGameGeek dataset. The chart uses D3 v7’s `scaleLinear` and `extent` to map the data to a 960x500 SVG canvas, with axes rendered via `axisBottom` and `axisLeft`. The React app loads data from a CSV file using `dsv` and binds circles to each game with a unique ID key.
