Neat demo of Visvalingam’s line simplification algorithm in JavaScript applied to a map of the US.
To simplify geometry to suit the displayed resolution, various line simplification algorithms exist. While Douglas–Peucker is the most well-known, Visvalingam’s algorithm may be more effective
and has a remarkably intuitive explanation: it progressively removes points with the least-perceptible change.

As Hammond explained what he did, the critic became agitated. Times are tough enough in journalism, he said, and now you’re going to replace writers with robots? “I just looked at him,” Hammond
recalls, “and asked him: Have you ever seen a reporter at a Little League game? That’s the most important thing about us. Nobody has lost a single job because of us.” At least not yet.

to generate the hash from the stock values. The resulting value is random and anyone can check the work to verify that it was chosen randomly.
Although, now looking back from the future I can't verify that they didn't generate this data after the stock quotes came out. And they're using MD5...
