-// dygraphs command-line performance benchmark.

-// Invoke as:
-//
-//   phantomjs phantom-perf.js 1000 100 5
-//
-// If the test succeeds, it will print out something like:
-//
-//   1000/100/5: 1309.4+/-43.4 ms (1284, 1245, 1336, 1346, 1336)
-//
-// This is mean +/- standard deviation, followed by a list of the individual
-// times for each repetition, in milliseconds.
