This interactive visualization displays cancer mortality trends in the United States from 1990 to 2019, plotting individual yearly death counts for fifteen distinct cancer types as colored dots. The scatterplot uses SVG circles rendered through React and D3, with each cancer type assigned a unique color and an interactive tooltip revealing exact death numbers on hover. Built with D3 scales (`scaleTime`, `scaleLinear`), axes (`axisLeft`, `axisBottom`), and event handlers, the chart reads from a CSV dataset filtered for USA records, making temporal patterns across cancer categories immediately comparable.
