This bubble chart visualizes the size distribution of turtles, plotting length on the x-axis and width on the y-axis. Circle size encodes height, while color distinguishes sex: blue for male and orange for female. Interactive tooltips appear on mouseover, displaying exact measurements. Built with D3 v7, the SVG visualization uses scales like `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal`, with data loaded from a CSV file and axes rendered via `d3.axisBottom` and `d3.axisLeft`.
