I have millions of points I want to draw on google maps ing from an array.

I was looking at circles example

However, the problem is circles are... circles. Is there some way to draw circles such that it is like a canvas so it doesnt really matter how many points I draw on it?

• 3 Have you seen the article Too Many Markers! in the Google Documentation? – geocodezip Commented Sep 3, 2016 at 11:52
• Grid-based Clustering looks great, but the docs dont show any examples of how to implement this. I was originally thinking some sort of canvas so that its just coloring pixels. I don't care about being able to interact with mouse. – Rolando Commented Sep 4, 2016 at 0:44
• By interact, I mean with interact with the point drawn. – Rolando Commented Sep 5, 2016 at 21:52
• 1 You need to make the question more specific to get a good answer. If you are looking for a heatmap the Google Maps API JS has one: developers.google./maps/documentation/javascript/examples/… , if you like the marker clusterer, but simply do not want the icons the solution is simple, just use github./googlemaps/v3-utility-library/tree/master/… and update the calculate function:stackoverflow./questions/12783250/… – kaskader Commented Sep 9, 2016 at 9:17

There are ready solutions for marker clustering like Markerclusterer or Markerclustererplus.

You can find these libraries on github:

https://github./googlemaps/v3-utility-library/tree/master/markerclusterer

https://github./googlemaps/v3-utility-library/tree/master/markerclustererplus

Sample pages and documentation are inside these repositories. Could it work for you?

I believe the answer is don't. That's too many markers. Per the table below (grabbed from geek.) you would have a screen with nothing but markers and no map, even if each marker were only 1 pixel each, which they aren't.
