This visualization presents a combined multi-series chart of the Breast Cancer dataset, displaying three variables across sample indices. Light gray bars represent smoothness_mean, scaled by a factor of 1000, while two overlaid polylines show radius_mean in steelblue and perimeter_mean in orange, using a shared y-axis for measurement values. The chart is rendered as an SVG using d3.v7, with data fetched remotely via d3.csv. Axes include grid lines created through SVG transforms and d3.axisBottom and d3.axisLeft, with a legend and axis labels clarifying the series. The dataset is sliced to the first 80 rows.
