Hi everyone,

I am doing a research on international oil and gas trade. The data table that I have looks like a typical train schedule. Each row represents oil exporting countries; each column represents oil importing countries; and the intersection between row and column represents volume of oil trade.

I found similar chart online but don't know exactly how to create it or even to describe it. I have attached the screen shot of the chart.

Any help will be very much appreciated.

Sincerely,
ZewSays
