A scatter plot displays online customer sales, mapping customer age on the x-axis against purchase value on the y-axis. Each circle’s fill color encodes the number of purchases, while the Time_Spent and Revenue_Total fields are bound to the circle’s rx and ry attributes, though the standard radius remains constant. The visualization uses D3 v5 with scaleLinear, extent, axisLeft, and axisBottom, loading CSV data from a GitHub gist and rendering as SVG circles.
