This reusable scatter plot visualizes the relationship between temperature and humidity from weather data loaded via a CSV file. It uses D3 v7’s `d3.csv`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render an SVG chart with steelblue circles that turn orange on hover. Axis labels are appended directly to the tick groups, and margins define the plot area within a 600x400 pixel container styled by external CSS.
