I use the Rutgers site, which has several tools

This link is old, but it gives a visual representation of how the rate varies over each chromosome

Note however that the cM unit is specifically designed to normalize the difference between hotspots and coldspots -- it's the *probability* of recombination. That is, for a 20cM segment, there is a 20% chance that a crossover point will occur somewhere within it, and on the flip side, there is an 80% chance that it will be passed on intact (if it survives the 50-50 chance of being passed on at all). There are some quirky regions of the genome where this doesn't work as well as expected. For instance, a chromosomal inversion, which might be found in some percentage of the population, will reduce the number of crossovers, since it won't align well with a normal chromosome.
