The various components of data visualization are:

  1. Time series- line charts, area charts, single or multiple variables behavior over time
  2. Ranking and comparison – Horizontal, vertical, grouped, or stacked bar charts
  3. Part to whole- Pie charts
  4. Correlation- Comparing two or three variables, scatter charts and bubble grapes
