Interactive time series
This visualisation offers some specialised information about a couple of economic indicators: cumulative percentage of change of some currencies against the dollar and the annualized percentage of change in exports. The information is displayed for six developing economies as a way to show the relationship between monetary policy (adopting floating currencies) and the change in the exports. It gives detailed information for each country in order to convey its message to a relatively specialized audience.

Benefits & pitfalls to avoid
- Line-charts imply that data is continuously changing. If your data is discrete you might consider a bar-chart instead.
Create your own
- Comparative charts are used to compare things such as performance, ranks, changes or characteristics. Basic comparative charts can be created in standard applications such as Excel using line graphs.
