Draws an image from a rectangular array of data by connecting the individual datapoints with polygons. #Arguments: `mat` - Row-major 2D array signifying the value of the datapoints. The X and Y coordinates of the datapoints are determined automatically, and optionally scaled using the `dimensions` argument. `num_rows` - Number of rows in the data array `num_cols` - Number of columns in the data a
