This scatter plot visualizes the relationship between average temperature and rainfall across multiple cities, using distinct colors and geometric shapes to differentiate data points by city. The visualization loads city data from a GitHub-hosted CSV file and renders it as an SVG using D3 v7, with linear scales for both axes. It employs `d3.symbol` with ordinal scaling to assign unique shapes to each city, while `d3.scaleOrdinal` with `schemeCategory10` provides color encoding. The chart includes labeled axes, a title, and a legend constructed from repeated symbol paths and text elements.
