Interactive chord diagram to visualize trade

What comes to mind when we think of trade? Quite possibly, exports, imports and trade balance. Is there a quick way to get this information without having to look at tables? Most of us would like to see how much a country imports and exports, which are the major trade partners, and what is the trade balance. We have introduced a d3.js based interactive Chord diagram to quickly visualize this information.

For example, here is a visual of Australia’s Exports and Imports for 2015. The chart shows top countries to which Australia exported or imported that year, and the remaining are bundled as “others”. Here is how you can interpret the diagram.

Each country has a different color. The length of the arc for Australia represents Australia’s total imports and the other parts of the arc show Australia’s exports to various countries. We can see the Import arc is slightly bigger than the Export arc and hence Australia has an overall negative trade balance.

WITS Trade Data Site: Five New Features

Where can you find the top trading partners for your country? Where can you find the top products exported to and imported from Indonesia? Where can you find just about any type of trade data?

The answers to these questions (and more) are available at our recently revamped World Integrated Trade Solution (WITS) site:  In previous versions of the site, users needed to login and query the data themselves. You still can.  And many still do to conduct much more detailed and sophisticated research and analysis on trade. But if you want to quickly look up or browse trade statistics like total exports, tariffs applied, top export, and import partners, the data has been pre-calculated and made available as Open Data.

“Thanks to the data I found on WITS, I successfully completed my PhD.  Really easy-to-use site and great upgrades.”

We have tried to make the new site more intuitive and accessible to the site’s users.  Our team – the Development Data Group (DECDG), the Poverty Reduction and Economic Management Network (PREM), and other World Bank units – worked in consultation with partners, including the United Nations Conference on Trade and Development (UNCTAD), the United Nations Statistics Division (UNSD) and others, to produce this site.  We hope you find the new site as useful as we do.
