The objective of this lesson is to learn different different data visualization techniques using country-level geo-demographic data.
Using the variable values shown in the data table at the bottom of the map, complete the color mapping table so that each color corresponds to a range of values
Paint each country by matching its variable value with a color in the color mapping table. Recommended practice is to use "cool" colors such as blue for low variable values. "Hot" colors such as orange and red should be used for high values.

Natural gas - proved reserves(cu m) Definition
This entry is the stock of proved reserves of natural gas in cubic meters (cu m). Proved reserves are those quantities of natural gas, which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.
