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.
