Have You Ever Seen a Bar Chart on a Map?

Welcome to the fascinating world of data visualization, where even maps can take the form of bar charts! I prefer to call this visualization a Skyscraper Map because you can picture these bars on a map as skyscrapers. Also known as a Bar Chart Map, this type of visualization brings your geodata to life, giving it the appearance of skyscrapers dotting a cityscape.

Why Use a Skyscraper Map?

You can use a skyscraper map to display geodata along with its corresponding values. This innovative visualization combines a map indicating various locations (be it a city, a country, or any geographical place) with a bar chart. Like a traditional bar chart, the height or volume of each bar in a skyscraper map is proportionate to the values it signifies.
