  • Trade or migration flow analysis between regions

Tips & Best Practices

  • Chord diagrams work best with fewer than 12 categories -- too many arcs become hard to read
  • Hover over an arc to highlight all its connections and dim unrelated ribbons
  • Use the "vibrant" or "rainbow" color scheme to make each category stand out clearly
