This visualization presents a dual-chart view of a GoodReads book dataset. The left panel is a scatterplot of average rating versus page count, with each book as a point. The right panel is a horizontal bar chart displaying the top 10 most popular publishers, with bars sorted by the number of books published and positioned along the average rating axis. Hovering over any data point or bar highlights all books sharing that publisher’s identity across both charts, while a dropdown menu adjusts circle opacity. The implementation uses D3.js v6, including scales for linear and band layouts, SVG circle and rect elements, and mouse event listeners.
