A 2D histogram is a nice way to to determine the distribution of two columns.

Desired solution

• Add a method histogram_2d to TablePlotter
• Parameters:
  • x_name: str - Name of the x-column
  • y_name: str - Name of the y-column
  • Keyword-only x_max_bin_count: int = 10
  • Keyword-only y_max_bin_count: int = 10
• Returns:
  • Image - The plot
• Raises:
  • _check_columns_exist for x_name, y_name
  • _check_columns_are_numeric for x_name, y_name
  • _check_bounds to ensure that x_max_bin_count and y_max_bin_count are >= 1
• Dark mode as described in Dark mode for plots #798.
• Make the plot consistent with scatter_plot, since it's just a variant of that with binning.
