Create a chord diagram showing trade flows between major economic regions

Here's a chord diagram showing trade flows between six major economic regions, with link thickness proportional to trade volume.

01

Supply groups and weights

Provide a source-target-value table or a matrix. Explain the unit, whether links are directed, and how repeated pairs should be treated.

02

Specify the intended format

Request a circular chord view when the ring arrangement matters. Check the generated result before describing its geometry or flow encoding.

Review totals and readability

Inspect category labels and weight comparisons. Ask for fewer categories or a matrix view if overlapping connections hide the data.

What is a chord diagram?

A chord diagram arranges groups around a circle and connects them with bands representing relationships or quantities. It is suited to comparing links among groups when their totals and relative connection weights matter.

When to compare weighted connections

Use a chord view for a compact overview of group-to-group relationships. The fixed trade example uses a Sankey layout with weighted links rather than a circular chord diagram, so its appearance should be described accordingly.

Rules for meaningful weighted links

  1. Define what a link measures. State the unit, period, and meaning of every supplied weight.
  2. Clarify directionality. Transfers from A to B may differ from transfers from B to A.
  3. Avoid double counting. Explain whether a symmetric matrix represents one undirected relationship or two flows.
  4. Keep category identity stable. Use consistent names and colors across labels and connections.
  5. Reduce crossings deliberately. If small links are grouped or omitted, explain the rule and preserve the relevant totals.

How MyMap organizes relationship data

MyMap uses your group names and weights to draft a relationship visualization. Ask for a circular arrangement if needed, and inspect the result; the available example demonstrates a related Sankey representation.

Common questions

Is the example a circular chord diagram?

No. It is a Sankey chart of illustrative regional trade flows. Its weighted links are related to chord-diagram data, but it does not use a circular ring layout.

What input format works for planning the visualization?

Provide a matrix or rows with source, target, and value. State whether direction matters and what the numbers measure.

What if the diagram is too crowded?

Reduce the number of categories, explain any grouping rule, or use a heatmap matrix. A dense ring of links can conceal comparisons that a table or grid makes clearer.
