Sankey Graph Style Small Multiples Choropleth Infographic

Data visualization infographic titled "Small Multiples" using CHOROPLETH MAP as the dominant visual element: a grid of small-multiple regional choropleth maps showing progress across several time points, with each map panel representing a different stage in time and each region shaded from low to high progress. Sharp map labels, legend labels, panel titles, scale labels, and any numeric ticks must all be in English. Use realistic plausible illustrative values, clearly marked as illustrative. Layout should emphasize comparison across panels to show improvement over time, with a consistent color scale and no misleading scale manipulation. Include a clear horizontal legend labeled "Progress rate (%)" with ticks "0", "20", "40", "60", "80", "100". Add concise region labels in English and small panel headers such as "Year 1", "Year 2", "Year 3", "Year 4". Include 4 key insight callouts around the maps, each with a small icon, a headline number, and a short interpretation in English: "72%" "Overall progress increased steadily" with upward arrow icon; "18 pts" "Largest gain in the South region" with location pin icon; "54%" "Mid-period level reached by most regions" with clock icon; "3 regions" "High-progress cluster by final period" with cluster icon. Add a small source/data-note strip at the bottom reading "Data note: Illustrative example. Figures shown are illustrative and not from a cited external source."
