It seems that IQ tests are always used with a normal distribution.

For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15.

I don't know whether IQ/intelligence is actually normally distributed, but it seems that IQ test results are.

To find a graph that better matches what you described, you might be interested in https://en.wikipedia.org/wiki/Cumulative_distribution_function and/or https://en.wikipedia.org/wiki/Skewness
