This scatter plot visualizes the relationship between a book's borrow count and its rating, with each point colored by genre. It displays the distribution of library books across these two quantitative variables. The visualization is built with D3 v7, using `d3.csv` to load data from a remote gist, `scaleLinear` for both axes, and `scaleOrdinal` with the Tableau10 scheme for genre colors. Points are rendered as SVG circles with tooltips, and a separate HTML legend is constructed by iterating over the unique genres.
