This scatter plot visualizes the relationship between sleep duration and stress level from a Kaggle dataset on sleep health and lifestyle, with points colored by gender and a legend for reference. Built with React and D3 v7, the chart uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `schemeTableau10` for categorical coloring, and `d3.axisBottom`/`axisLeft` for ticks. Hovering over a point reveals a tooltip with details on person ID, gender, sleep, stress, and sleep disorder, rendered as SVG circles via a `for..of` loop.
