Point map with clusters

Written by

  • Sections in the wizard
  • Creating a point map with clusters
  • Recommendations

A point map with clusters differs from a regular point map in clustering adjacent points. On the map, a cluster is represented as a donut chart with the number of points displayed in the center.

The behavior of points varies depending on the map scale:

  • When scaling down, points are clustered.
  • When scaling up, the distance between points increases and a cluster is automatically split into smaller clusters and/or individual points.

If a map with the selected scale only contains a single point, it's not clustered. In this case, instead of a donut chart, you'll see a point just like in a regular scatter chart.

Clustering on a map improves visualization when there is a large number of points. For example, if you want to show the location of all stores in a city on a map with clustering, points on the map won't overlap.

Restrictions:

  • The Points size, Tooltips, and Signatures sections only apply to individual points.
  • The Colors section only lets you add a dimension.

Description
Points with clusters (Geopoints) Measure with the type Geopoint.
Points size Measure. Sets a point size depending on the measure value.
Colors Dimension. Affects the intensity of point fill.
Signatures Measure. Displayed as text on a point. When used, points size control is blocked.
Tooltips Dimension or measure. A tooltip that appears when you hover over a point.
Layer filters Dimension or measure. Used as a filter for the current layer.
Chart filters Dimension or measure. Used as a filter for the entire chart.

Creating a point map with clusters

  1. On the Yandex DataLens home page, click Create chart.
  2. Under Dataset, select a dataset for visualization. If you don't have a dataset, create one.
  3. Select the Map chart type.
  4. Select the Points with clusters (Geopoints) layer type.
  5. Drag a dimension with the Geopoint type from the dataset to the layer type selection section.
  6. Set the size of the points displayed on the point map. Drag a measure to the Points size section or click in the line with the section name.
  7. Colors the points on the map. Drag a dimension to the Colors section.
  8. Add tooltips to show the dimension and measure values when hovering over a point.

You can also:

  • Add, rename, and delete a layer.
  • Reorder the layers within a layer type.
  • Apply a filter to the whole chart or one layer.

Recommendations

  • Use color palettes corresponding to visualization aims and objectives.
