This bubble chart shows the correlation between average temperature, humidity, and pressure across 25 U.S. states. Each circle’s x-position maps to temperature, y-position to humidity, and radius to pressure, with colors assigned per state via a custom ordinal scale based on `d3.interpolateTurbo`. The visualization is rendered with SVG and includes interactive tooltips on mouseover and a legend for pressure values. Data is loaded from a CSV file using `d3.csv`, and axes are generated with `d3.axisBottom` and `d3.axisLeft`.
