Overview

This dataset is an extended version of the classic Iris dataset — one of the most widely used benchmarks in machine learning and statistics. The original four flower measurements (sepal and petal length and width) are preserved and augmented with ecological context (elevation, soil type) and engineered features (area ratios, curvature, texture) to support richer analysis and more advanced classification experiments.

The goal is to classify each sample into one of three iris species: Setosa, Versicolor, or Virginica.

Property	Value
