Create a map that provides a clear market overview – in seconds.
You may be familiar with bubble charts, where volume of data is expressed by circle sizes on x and y graphs. eSpatial offers something similar, except that we express data in the form of a bubble map.
Why express data in a bubble map?
A bubble map is a simple, fast and effective way to discover and reveal data trends. That’s why such maps often accompany news articles or appear in annual company reports. They are highly effective in lending support to commentaries, results or projections.

Summarize and aggregate
Bubble maps are also motivating (and sometimes emotive!) because they summarize and aggregate data derived from specific geographic regions, reducing it to a single expression (a bubble can represent anything from a zip code to an entire country). They are also simple to understand: a large bubble indicates high occurrence, a small bubble indicates low occurrence.
Bubble maps can compare and contrast
By using two sets of data on a bubble map, you may also productively compare sets of data that are integrally linked to one another. An example would be to have one dataset that shows college rankings with average salaries of graduates of each college. Such positioning of data can tell a story that would not be obvious from simply reading data from a spreadsheet.
It doesn’t have to be a bubble
Although it’s called a bubble map, you are not limited to using “bubbles” as map point markers. eSpatial offers a range of marker to choose from. Each one will be automatically scaled to express the level of “bubble data” on your map. You can also use your own graphics – including logos – on an eSpatial map. They too can be scaled to express the relevant values.
Make data stand out
Bubble maps are a great way of visualizing data. Because they express summarized information, pertaining to a geographic region, it is sometimes better to change the style of map on which the data appears. The larger the geographic region that the bubbles represent, the simpler the basemap need be. You can experiment with eSpatial’s growing range of basemaps – roadmap, satellite, terrain, etc – to find the best way to graphically express the message contained in your data.
