This scatterplot visualizes the relationship between sleep duration and stress level, with each point representing a participant. The x-axis shows sleep duration in hours, while the y-axis tracks stress levels. Semi-transparent steelblue circles, each with a radius of five pixels, reveal the distribution and density of data points. Built with D3 v7, the visualization uses `d3.scaleLinear` for both axes, `d3.extent` for domain calculation, and `d3.axisBottom` and `d3.axisLeft` for tick marks. The data comes from a sleep health dataset loaded via `d3.csv`, and the chart is rendered as SVG within a styled HTML page.
