Five circles in a horizontal row show a small dataset of numeric values, sized proportionally and shaded with a sequential color scale from light to dark green, with each value labeled beside it. The code uses D3 v4’s data join to bind an array of five numbers to SVG group elements, then appends circles and text. Circle radii are scaled by the data value, and colors come from a hardcoded array, while dimensions are set directly on the SVG.
