This reusable scatter plot explores the Digital Usage dataset by mapping screen time hours to productivity scores, with color distinguishing application categories such as Work, Social, Gaming, and Education. A regression trend line summarizes the negative relationship, while tooltips reveal exact values per point. Built with d3.v7, the chart uses d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.scaleOrdinal for scales and axes, with SVG circles for the marks. The design accepts configurable properties, enabling the same structure to be reused with different quantitative pairs.
