This line chart displays projected delivery dates by report year for multiple Social Security Number (SSN) groups, with each line representing a distinct category color-coded using `d3.scaleOrdinal` and `schemeCategory10`. The chart includes labeled axes, a title, and a color legend rendered as SVG circles and text. It uses `d3.line` with `curveBasis` smoothing, `d3.nest` to group data by SSN, and `d3.axisBottom` and `d3.axisLeft` for ticks. Data comes from a CSV of modified SSN records, parsed with `d3.csv` and converted to JavaScript `Date` objects.
