In a couple of recent articles I've been using Three.js and d3.js to create 3D maps and visualize metrics. In the last week I combined a couple of these techniques to create a visualization of the financial/debt crisis in the Eurozone:
In this timeline I show how the interest rates for the long term bonds change over time for the Countries of the Eurozone. This is the interest rate countries pay to refinance their debts. Why is this interesting? This interest rate is a very good indication of the financial stability of a country. Is the rate high, then refinancing debt will cost more and more and interest payments will go up. A situation which, at certain percentages, will bankrupt a country.
In this visualization the following is shown:
This timeline uses the following techniques:
In a couple of future articles I'll go into more detail on how the various libraries are used.
