    color_grouping_type: [party|year|none]
    custom_party_colors: # REQUIRED: color_grouping_type: party
      [Parliamentary group value]: [color hex code]
      [Parliamentary group value]: [color hex code]
      [Parliamentary group value]: [color hex code]

Some info about the yml

1. [wikipedia link]: Wikipeda page that contains a table with the list of parliament members of some year [example
2. [html table header]: The Table Header
   1. First click View Page Source on the wikipedia page
   2. Spot the table with the parliament members
   3. Copy the header of the table - usually it starts with a <thead> tag
3. [Name Column]: The name of the column that represents the members' names
4. [Parliamentary group column name on wikipedia]: The name of the column that represents the parliamentary groups' names
5. [Parliamentary group column name to be shown on on plot]: The value with which you want the previous attribute to be replaced on the plot
6. [column name to ignore]: If in the page source there is table column with the attribute colspan="2", the add its name here
7. [tag enclosing the table]: The tag name that encloses the header along with rest of the table - usually <table> or <tbody>
8. [Output Plot Name]: The name of the plot
9. [path in which the plots are going to be saved]: Save path of the plot
10. [Parliamentary group value]: The name of the parliament group for which you want a custom color
11. [color hex code]: The hex code of the custom color - should be enclosed in double quotes e.g. "#4974BB"

Run it

parliament_members_sankey -c CONFIG_FILE [-l LOG_FILE] [--debug] [--help]

or

python3 main.py -c CONFIG_FILE [-l LOG_FILE] [--debug] [--help]
