Content

• What is data visualisation?
  • Art of representing data graphically
• Why learn data visualisation?
  • Humans are visual creatures
  • We can derive insights more easily through visual clues than numbers
  • It will help you communicate better
• How data visualisation is used in machine learning
  • Feature selection
    • Select only useful features for a simpler, faster model
  • Model Evaluation
    • Know if your model fits the problem well
  • Communication
    • Present the results to non-expert/-technical audience
• How to do data visualisation?
  • Use libraries, or proper visualisation software
    • Matplotlib, seaborn, R, Tableau
  • Beware of common mistakes
    • Graphs should support your point, not be the point
    • Avoid colour abuse
