This interactive scatter plot visualizes library book data, showing relationships between numeric attributes like borrow count, rating, pages, and year, with points colored by genre. Users can dynamically switch the X and Y axes via dropdown menus and adjust point radius with a slider control. The visualization is built using a reusable D3.js module with a closure-based API for configuring scales, axes, and accessors. It employs D3's `d3.csvParse` for data loading, `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `schemeTableau10` for color encoding, and SVG rendering with hover tooltips.
