A decision tree repeatedly splits the feature space along one axis at a time, carving it into rectangular regions each assigned a class. Deeper trees fit more complex boundaries but risk overfitting. Tune the splits to separate the two colors. Educational tool.

Governing equation

Gini = 1 - i \sum p_{i}^{2} \Rightarrow accuracy = 100%

Reading this result: Two axis-aligned splits near the center carve the plane into four boxes that match the classes — depth 2 is exactly enough to solve XOR.
