A choropleth map is another name for a heat map – it visualizes the level (or intensity) of measurable data in specific geographical areas.
Benefits of a choropleth map
For instance, imagine you wanted to see – at a glance – the most heavily populated areas of a state, per county. You would assign each county with a shade that represented the level of population. A sparsely populated county might be represented by a light pink colour, while a heavily populated county would be represented by a rich red shade.
A choropleth map is a great business insight and planning tool. Just taking the expression of population, as an example, you can see how such a map could help with simple business decisions, such as where to locate your business headquarters – or sales outlets, if you were running a retail business.
But when you start to layer other data onto a choropleth map, that’s when things become really interesting. This might be your own data or you could source it from elsewhere, such as government agencies or commercial data providers.
