Where are your addresses concentrated?
Customers, orders, incidents, donors, job sites: with a few hundred rows, a map of pins turns into a blob. What you want to know is where they gather, and how many fall in each area.
The free map answers that with clusters. Nearby points are grouped into a circle that shows their number: bigger circles for bigger groups. Zoom in and the clusters split, down to single points at street level. Click a cluster to zoom to it.
Understanding map density
- Every row counts. Ten rows at the same address make a cluster of ten, so repeat customers or repeated orders count as many times as they appear. Each address is still looked up only once.
- ZIP codes and postcodes count at their center. A list of ZIP codes gives a fair picture at the scale of a city or a state; for street-level density, use full addresses.
- Check the outliers. A cluster in an odd place is often a geocoding mistake: points marked “to check” are listed under the map, with the reason, and can be dragged to the right place.
Compare groups
If your list has a column with a few distinct values, such as Product, Year, Channel or Status, color the points by it. The legend shows how many rows each value has. Zoom into a cluster to see which colors make it up.
The heat map layer (Pro)
A heat map shades the map by density instead of grouping points, which reads better with thousands of rows. It is part of Pro ($19 for 7 days), with larger lists and the download of your data with latitude and longitude. Clusters, colors and the PNG image stay free.
Private
Your file stays in your browser. Only the text of each address is sent to place the points; the other columns, such as amounts or names, never leave your device.
Questions
Is there a heat map today?
Yes, with Pro ($19 for 7 days). The free map groups nearby points into clusters that show how many rows they hold, which already answers "where are most of them?".
Can I color points by category?
Yes. Color the points by a column such as Product or Year, and zoom in: each cluster splits into points of their color.
Are rows at the same address counted?
Yes. Every row is a point: ten orders at the same address count as ten points. The address itself is looked up only once.
How many addresses can I map?
Up to 500 rows per map for free, up to 25,000 with Pro ($19 for 7 days).
