This example shows the distribution of carbon emissions per employee across companies, grouped by emission scope (1, 2, 3). For each scope, a box-and-whisker plot summarizes quartiles, median, and outliers, while individual companies appear as colored circles, jittered vertically to reduce overlap. The visualization uses D3 v4’s `d3.csv`, `d3.nest`, `d3.quantile`, and `d3.scaleBand` to structure and layout the data, with a sequential color scale from `d3.interpolateRdYlGn` mapping emissions intensity. Circles include mouseover tooltips, complementing the SVG-rendered boxes and axes.
