Relative visualization merits of Cartodb.com versus Google Maps and other mapping applications?

One of the challenges I faced in developing Wikitree's Percheron Immigration Movement project was fullfillling my desire to visualize the location of origin of the 300-odd Percheron pioneers who immigrated to New France. The project has involved developing standardized profiles of Percheron pioneers culled from reputable lists available from Gervais Carpin's thesis as well as from the 2 lists at perche-quebec.com and perche-canada.net websites. I eventually elected to realize this mapping visualization by using a cartodb.com bubble map as background layer then using Paint to manually define 17th century villages along with the number of pioneers for each village and associated notes, title and  background layer masking.

The end product is the map shown at http://www.wikitree.com/index.php?title=Category:Percheron_Immigration , which is consistent with the Carpin-number-centered wikitable immediately below and, futher below, the alphabetical list inherent with the Percheron Immigration Category derived from profiles.

While more labor-intensive than can be made from Google Maps, the cartodb.com approach is the only one I know of that caters for bubble size related to number of profiles for any given location of origin.

It appears that cartodb.com is free for colour-based sub-layers involving no more than four colours, where I show three sub-layers or colours in my case.

Hi Claude,

It seems the link to the Category you have in your post shows a page that doesn't exist.

Also: I don't know if it can be used for your purposes, but there is Open Street Map. It's open source and collaborative in nature.

With comma separated by a space, the link is now working. I am not familiar with Open Street Map but it seems crucial to me for solution to such demographic issue as Percheron Immigration movement that size of bubble be available. I am basic done with solution using cartodb.com so Open Street Map is to large extent academic. Use of 'Street' in Open Street Map does not bode well for this high-visualization problem. Cartodb.com appear to be free for my purposes.

Nice map!

OSM has a lot of capabilities. I don't think it's strictly related to just streets; it's just part of the name. It's free and open source. Perhaps it might be useful in the future for you.

I looked at OSM and will keep it in mind. I encourage you to view the youtube. https://www.youtube.com/watch?v=hVimVzgtD6w, by Hans Rosling entitled,

It gives an excellent sense of the power of bubble-based to quickly and powerfully visualize demographics. 

Eric,

I notice on closer inspection that the cartodb.com background maps such as the one illustrated in this G2G discussion are shown as being copyright openstreetmap contibutors!

Which makes it evident that cartodb.com also 'has a lot of capabilities'.
