    DATA VISUALIZATION GOOD PRACTICES
    ● Pie charts: only if they have 3 or less slices;
    ● Bar and columns charts: Always show the origin (zero line);
    ● Horizontal bars are easier to read than vertical ones for categorical, non-time sensitive, data (and nominal
    variables in general);
    ● Always add a title to visualization;
    ● Always label axes;
    ● Add callouts if you want to highlight some information;
    ● Avoid 3d charts
    ● Reference data sources.

    OUTPUT WINDOW
    You can save you Outpt window as a separate file.
    .SPV files do not include the dataset, but can very helpful in case you want to share a chart with someone else on
    your team.
