This scatter plot visualizes the relationship between temperature and humidity from a plant growth dataset. The visualization uses D3 v7 to render circles on an SVG canvas, with a linear scale mapping temperature to the x-axis and humidity to the y-axis. The code loads CSV data from a GitHub gist, parses the numeric fields, and draws blue circles with a radius of five pixels. Axis labels and ticks are generated using the d3.axisBottom and d3.axisLeft functions, with the chart configured with a 50-pixel margin.
