This scatter plot visualizes the relationship between average temperature and humidity across ten cities, with each point colored by continent. The visualization uses D3 v7 to render SVG circles, with `d3.scaleLinear` for both axes, `d3.scaleOrdinal` for the categorical color mapping, and `d3.axisBottom`/`d3.axisLeft` for the tick marks. A static legend groups the five continents, while the data comes from a hardcoded array in the script.
