Is there an easy-to-use Cartogram-creating program that Wikipedians can use to create maps without complicated fair use issues? There are certainly some cartogram generators online, but none apparently easy enough for me to use. (I'm dumb by the way.) --- Rogsheng (talk) 07:13, 15 January 2008 (UTC)[reply]
How about including Borden D. Dent in the bibliography?--131.155.68.6 13:14, 12 January 2007 (UTC)[reply]
How about using one of these cartograms for the US election instead?. They're generated by a different algorithm, and appear to be visually more understandable. The currently displayed image isn't bad, but it somewhat looks like it's filled with bubbles.
The claim that "cartogram" does not refer to any statisitical map seems highly suspect. Webster's 7th says,
a map showing statistics geographically
, which could be taken either way. The Collaborative International Dictionary of English v.0.48 gives the slightly more definitive:
A map showing geographically, by shades or curves, statistics of various kinds; a statistical map.
Finally, no less than Mark Monmonier [1] uses the term to refer to maps which are geometrically distorted for the sake of the message, calling the specific form espoused here an area cartogram. I suspect that in using such strong wording the original author was trying to distinguish between choropleths and cartograms. Any thoughts before I take a chainsaw to this entry? --Belg4mit 19:06, 7 April 2007 (UTC)[reply]
The article currently states that travel time is a typical example of a cartogram, but I have been unable to find one. Everything I found uses overlays on spatially unchanged maps. I would expect that a car travel time map would shorten the freeways and extend city roads (because they have lots of traffic lights), making rural areas look closer together and cities more spread out (five miles in the city can take an hour, but the same hour on the freeway in Vermont could get you 80 miles). Can anyone provide a single example? I think a map like this would be beautiful. Best would be a dynamic map that plots time from a single starting point, and would allow you do move the starting point for a new map. -96.233.17.206 (talk) 18:53, 18 September 2010 (UTC)[reply]
Dorling cartograms deserve coverage. --Belg4mit (talk) 02:42, 7 August 2011 (UTC)[reply]
Although it's nice to have a non-population based cartogram (at least not strictly scaled by population), the amount of space it takes up in this relatively small article has a negative impact on legibility. --Belg4mit (talk) 04:48, 7 August 2011 (UTC)[reply]
I do have some issues with this map and calling it a cartogram. If (as it appears) it shows relative data (i.e. per capita) in the size of a country, this is a false use of the concept of a cartogram, which is meant to show absolute data. Think of it as a geographic version of a pie chart: only use data that you can also use for drawing a pie chart. Also, it is problematic to show negative and positive data within one cartogram transformation. Again, think of a pie chart before turning numbers into cartograms. This is not a valid cartogram in its core meaning and should not appear in the related article about cartograms. I suggest replacing this cartogram with a more appropriate example. 31.185.240.3 (talk) 22:37, 25 February 2013 (UTC)GeoGuest[reply]
For the table in the "Algorithms" section, could someone make an extra column with image examples for them/explanations of how they work? because im not a cartographer or anything, i dont understand or know what they are — Preceding unsigned comment added by 108.31.15.173 (talk) 17:24, 29 August 2020 (UTC)[reply]
I just completed a significant amount of work on this page, including: a real introduction, history, categories of cartograms, and lots more citations. Two things I did not work on:
I reset the quality ratings on this page; would love some more editors and a new rating review! Bplewe (talk) 22:40, 15 November 2020 (UTC)[reply]
