This visualization displays statutory employer costs as a percentage of gross salary for 76 countries, grouped by region, with each bar labeled by country and a "≥" marking statutory floors. The chart uses D3.js v7's `d3.csv`, `d3.select`, `d3.groups`, `d3.scaleLinear`, and `d3.axisBottom` APIs to render SVG output. Data comes from an EOR Scope CSV export, and the visualization highlights regional groupings with explicit floor values rather than a global ranking.
