Introduction

The Iris Dataset

The Iris dataset is a classic dataset used to explore relationships between flower measurements.

It contains measurements of:

  • Sepal length
  • Sepal width
  • Petal length
  • Petal width

The dataset contains three species:

  • Setosa
  • Versicolor
  • Virginica

Interactive Visualization

Sepal Length vs Petal Length

What We Can Observe

Key Observations

The interactive plot shows that:

  • Setosa forms a clearly separated cluster.
  • Versicolor occupies an intermediate range.
  • Virginica generally has larger petal measurements.
  • There is a strong relationship between sepal length and petal length.

Use the Plotly controls to zoom, pan, and inspect individual observations.

Conclusion

Summary

The Iris dataset provides a simple example of interactive data visualization.

Plotly allows us to explore the relationships between variables interactively rather than viewing only a static graph.
