DBSCAN is like a kid in a playground who says:
“Main group tab banata hoon jab paas-paasmey kaafi bheed ho.”

✅ No fixed K (unlike K-Means). ✅ Finds weird shapes (curves too). ✅ Leaves lonely points as noise.

Core idea: A point draws a bubble of radius ε. If bubble has at least minPts friends → it becomes a CORE point.

Try Two Moons → K-Means struggles, DBSCAN shines.

Rule: Small ε = many points become noise. Big ε = everything becomes one gang.

Big minPts = stricter gang rule (more noise). Small minPts = easier gangs.

1) Press Start (watch scanning beam).
2) When a point becomes CORE, its bubble glows.
3) Cluster expands like a spreading paint wave.
4) Click inside arena to add points — DBSCAN will react.
