Point Density

In this view, the map displays a representative selection of the currently visible data points, taking into account all of your filters. As you move around the map, the Data Explorer shows you enough data points to get an impression of the geographical patterns in the underlying data, displaying overlapping points with increased intensity. To inspect individual points, zoom into a map area.

You can investigate clusters within your data by zooming in and out of the map using your mouse or trackpad.

You can select this view by clicking the Point density map button:

Visualizing the point density of continuous numeric data (color-by-value)

If a data layer property contains continuous numeric data, you can visualize the data points as a point density view. For your selected geographic area and time range, the Data Explorer displays the data points for this property, colored by value. For example, say your data layer includes an age property. If you want to explore the range of ages, click on the property's point density button for the age property.

Notice that the age ranges in the palette are colored by value and these colors are shown on the map.

To find out the exact value of a data point on the map, click on it.

Visualizing the point density of categorical data (color-by-category)

If a data layer property contains categorical data, you can visualize the data points as a point density view. For your selected geographic area and time range, the Data Explorer displays the data points for this property, colored by category. For example, say your data layer includes a property that records where shipping vessels are registered. If you want to explore this data property, click on the property's point density button to see vessels colored by their registered nationality.

Notice that the age ranges in the palette are colored by category and these colors are shown on the map.
