If we try to do a wider range, wolfram alpha can't handle it and gives us a crazy plot, but a true graph of the function would be a flatline everywhere except for tiny inverted parabolas at factors, multiples, and sometimes points of interest like the square root and the average of the prime factors

Here is the same graph on the 60.9 to 61.1 range:

The way you exploit this function is you add an arbitrarily small constant and do some transformations so we only focus on the part of the graph that pokes out above 0 and flat-line everything else. There are many ways of doing this, one looks like this:

That's not a #bug, it's an undocumented feature!
