A lot of maps on the internet fail at this in various ways. {{en}}<br />
{{minor|That's why [[User:Elie|I]] made a [[Code:isochromic.c|small program in C]] for making isochromic images. I have not written any tutorials/documentation yet, unfortunately. I still have a lot more maps left to make first.}}<br />

==Examples of isochromic== <!-- TALK: maybe actually have one heading "examples" and then for each example, show an isochromic vs non-isochromic version --><br />

<!-- TODO: add this in after adding other examples first:<br />
Suppose we want to show where the world's deforestation is happening. We can use deforestation's CO2 emissions as a proxy.<br />
[[File:Annual_CO2_emissions_from_deforestation,_global.png]]<br />
Just one problem: It's not isochromic - it doesn't show equal red for equal deforestation. It over-emphasizes larger countries - so if a cluster of small countries were to add up to more deforestation than a big country, you wouldn't see it.<br />
If we wanted to make a proper isochromic map: For each country, divide its deforestation rate by its total land mass. The result should determine the shade of red to color the country.<br />
