A Choropleth Map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region.

An exploded view drawing is a diagram, picture or technical drawing of an object, that shows the relationship or order of assembly of various parts. It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram. An object is represented as if there had been a small controlled explosion emanating from the middle of the object, causing the object’s parts to be separated an equal distance away from their original locations.

A Bubble Map Chart is simply a combination of a bubble chart data visualization and a map. It is used to visualize location and proportaion in a simple way.

Pin maps are used to display geospatial data on a map. The basic use is to pin locations and give them labels/descriptions. It can be combined with proportional icon area chart to illustrate numeric values, shades of colours to display degrees, or icons to present different groups.

Bar chart on a map is a combination of a map with locations and a bar chart. It is useful when presenting geospatial data along values. The location could represent a city, a country or any other kind of location. Like a bar chart, the height or volume of each bar is proportional to the values it represents.

Flow Maps in cartography can be defined as a mix of maps and Sankey diagrams, that show the movement of quantities from one location to another, such as the number of people travelling, the amount of goods being traded, or the number of packets in a network.
The width of the connections shows the quantity. Sometimes you flow maps with arrows to display the direction of the movement.
The most famous example of a flow map, is Minard’s map of Napoleon’s disastrous Russian campaign of 1812.

A topographic map is a detailed and accurate graphic representation of cultural and natural features on the ground. A topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a combination of two line segments that connect but do not intersect; these represent elevation on a topographic map.

Connection Map is used to display network combined with geographical data. It can be used for visualising flight connections, flow of import/export or migration, any kind of connections between different locations. By combining thickness, colour, or pattern to the lines or adding another type of visualisation (for example, bar chart or dot plot), you can add numeric values to Connection Map. It is related to a Flow Map but display no quantitative values between the connections.

Connection Map

A Pie Chart Map is simply a combination of a Pie Chart data visualization and a map. It is used to visualize location and numerical proportion in a simple way. Sometimes you will see a combination of both Pie Chart, Map and Bubble Chart. Where the size of the Pie Chart circle allows one more dimension to the visualization.

A dot density map is a map type that uses a dot or another symbol to show the presence of a feature or phenomenon.
In a dot density map, areas with many dots indicate high concentrations of values for the chosen field and fewer dots indicate lower concentrations.
Each dot on a dot-density map can either represent one single recording of a phenomenon (one-to-one) or represent a given quantity of it (one-to-many).

Dot Density Map

Cartograms distort the shape of geographic regions so that the area directly encodes a data variable. A common example is to redraw every country in the world sizing it proportionally to population or GDP. Can be done by circles, squares or distorted maps by manipulating the initial map.
Primarily used to visualize data related to countries, regions or states, for example votes in elections, population or income.


Isoline maps show a range of quantity. They show data as a third dimension on a map, making them good for mapping surface elevations or for weather data. Radar maps, temperature maps and rainfall maps are all isoline maps.

Route Map is used to displace a series of geographical data with a start point and an end point. It is useful to show directions from start point to destination or to visualise traces of a run or a trip. It can be placed on an actual map or used solely. By combining thickness, colour, or pattern to the lines, you can add categories to Route Map. It is also possible to combine with time, icons or other values to the points.
