This scatter plot visualizes population estimates by state and year, using a reusable d3.scalePoint for the x-axis, d3.scaleLinear for the y-axis, and d3.scaleOrdinal with d3.schemeTableau10 for color coding by year. Symbols vary by year through d3.symbol with circle, square, triangle, diamond, and star shapes. The SVG renders axes with d3.axisBottom and d3.axisLeft, includes rotated state labels and a legend, and pulls data from a CSV of Texas population estimates.
