This example shows a scatter plot of phone battery life versus weight, with each phone brand represented by a distinct symbol shape. The plot encodes battery life on the x-axis and weight on the y-axis, while a legend identifies each brand’s symbol. The visualization uses D3 v7 with SVG rendering, leveraging `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `d3.symbol` for categorical shapes, and custom ES6 modules for axes and legend rendering. Data comes from a CSV file listing ten phone models and their specifications.
