This tool produces a histogram (i.e. a frequency distribution graph) for the values contained within an input raster file (`input`). The histogram will be embedded within an output (`output_html_file`) HTML file, which should be automatically displayed after the tool has completed. The user may optionally specify the number of bins (`num_bins`) used in the histogram. If unspecified, this is calculated as:

`num_bins = ((rows * columns)).log2().ceil() + 1`
