19. Photo: Startup Weekend Hackathon. Nov.2014 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.
