Scatter Plot - Iris Dataset

Scatter Plot Description

Dataset: Iris Flower Dataset (150 samples)

Visualization Type: Scatter Plot with color encoding by species

X-axis: Sepal Length (cm) - The length of the sepal (outer part of the flower)

Y-axis: Sepal Width (cm) - The width of the sepal

Color Channel: Species (Setosa, Versicolor, Virginica)

Insights: This scatter plot reveals the relationship between sepal dimensions across three iris species. The Setosa species (blue) forms a distinct cluster with shorter but wider sepals, while Versicolor (orange) and Virginica (green) show more overlap but tend toward longer, narrower sepals. The visualization demonstrates how position (x,y coordinates) and color channels can effectively reveal patterns and groupings in multivariate data.
