This bubble chart shows the correlation between average temperature, humidity, and pressure for various U.S. states. It plots temperature on the x-axis and humidity on the y-axis, while encoding pressure through both the size and color of each bubble, with a legend for pressure values and a color scale for states. The visualization uses D3.js v7, leveraging `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` with `d3.interpolateTurbo` for color mapping, and custom tooltip handlers for interactivity. Data is loaded from a CSV file, and hovering reveals each state's name.
