# What is the Bar Chart visualization?

Bar Charts allow you to see bars of aggregated data. By clicking over a bar you can see the name of the aggregation it represents (e.g. district name) and its indicator value. The bar chart is useful when you want to compare aggregated values across indicators and geographies for the entire selected time period.
