Observations in World Bank
This tool can display charts based on the observations in the World Bank Indicators dataset.
How-to use this tool: select an indicator, then select one or more countries, or an observation year. Line chart is used to view observation values in countries, over a time period for an indicator. Geo chart is used to view observation values for a time period for all the countries in the world.
Charts are currently created using the Google Chart Tools. That might change in the future given how I take this tool forward, as I have to consider performance, and complexity of chart creation given observations from multiple datasets. At this time, I consider this tool as an experiement.
