This scatter plot visualizes birth rate trends for U.S. states, comparing 2017 values on the x-axis against 2018 values on the y-axis, with each state represented as a green dot. The visualization uses D3.js v6 to load CSV data from a GitHub gist, parse it, and render an SVG chart with labeled axes. The code implements linear scales with `d3.scaleLinear`, draws axes via `d3.axisBottom` and `d3.axisLeft`, and creates circles with `append('circle')`. Interactive mouseover events log state-specific data to the console.
