So there are two approaches coming from a cartographic standpoint that could work in your situation, but it depends on what you want the user to do with these markers. The first involves the user using these as just a visual aid meaning they would have no interactivity and be just static images to inform the user. In this case, I would a pie chart marker ...

You could keep a single pin as the marker but organise a simple visualisation within the pin so the data stays 'contained'. You could increase the size of the pin a little if you have more items to show. For example: Or moving the icon outside the inner circle: You could change the shape of the pin: And you could colour the pin according to the ...

The better solution is to display markers which are aligned to the map scale. Map creates the context for the markers, so when map is zoomed-out, it has no sense for user to see separate markers, as at the given scale exact locations are lost within the large geographical area. Remember, the marker itself is the mean to point to exact location. So be ...

Maybe you could combine the pin with a checkbox and give the pin two clearly distinguishable states (checked, unchecked and maybe differentiate with a colour too, see image). This allows the user to make a selection of different locations/items in one view. It should be clear what can be done with the selected items and I suppose there is a button somewhere ...

A clear way to demonstrate groupped locations in a full size map is to provide a fix positioned list of your groups in a corner of the map, each group name has a color, assign that color to the pins related to each of those group names, default transparency for pins must be about 50-60%. Then once you clicked on a group name, the group name title can get ...

So I actually did my Masters thesis research on the default zoom level and level of detail that users prefer when working with way finding and identification tasks. Overall, users tend to prefer a large scale map (more zoomed in) and a generalized view (as opposed to satellite imagery). However, there are exceptions to this. When setting the initial zoom, ...

Sigh... The age-old "how do I do clustering on a map correctly" question. Short answer: Clustering doesn't work. There is no such thing as good clustering UX, as clustering is not good UX. The reason is simple: The user is either interested in an area, or a point. He might be interested in the density of an area (population, number of ice cream shops ...

This is a common problem with maps. There is a solution called MarkerClustering. You can read more about it on the web. Here are some starting points: https://developers.google.com/maps/articles/toomanymarkers And here is an example of its implementation: http://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.388.html

You're already communicating two dimensions of information with your icons: Number of likes Type of icon (question, post) You want to add a third dimension (multiple posts per icon). It's going to be difficult to do this because: Having icons communicate more than 2 dimensions of information is not a good idea. You are going to need some way to ...
