Introduction

Welcome to the interactive exploration of the classic Iris dataset!
In this presentation, we’ll use Plotly for dynamic visualizations.

About the Iris Dataset

  • Measurements of 150 iris flowers
  • 3 species: setosa, versicolor, virginica
  • Features:
    • Sepal Length & Width
    • Petal Length & Width

Required Libraries

Key Takeaways

  • Setosa is distinctly different in petal features
  • Petal.Length and Petal.Width are strongly correlated
  • Plotly makes EDA fun and interactive
  • Interactive plots = better insight & presentation
