This line chart shows the relationship between diamond carat weight and depth percentage, using a filtered subset of a diamonds dataset (every fifth point) loaded via `d3.csv`. The SVG visualization maps carat weight to the x-axis and depth percentage to a fixed 50–80 range on the y-axis, with a blue `d3.line` path connecting sorted data points. Gridlines from `d3.axisLeft` provide reference, while axis labels and a title are rendered as SVG text. The chart uses `d3.scaleLinear` for both scales and styled SVG elements for rendering.
