This example visualizes monthly average price histories for multiple commodity series, drawing small-multiple line charts across a grid. Unlike typical faceted plots, the chart labels are positioned using a constraint relaxation algorithm borrowed from the Dorling Cartogram approach: each label is simulated as a charged particle that repels neighbors and is pulled toward its target data point, iteratively reducing overlaps. The result is a clean, readable set of annotated mini time-series charts, with SVG rendering and D3 v2, showing how constraint-based layout can untangle dense labeling in small multiples.
