Step 1 / 10

Empty coordinate plane with range $[-1,10] \times [-1,10]$ . We will build a convex hull step by step.

Step 2 / 10

Add first point at $(1,2)$ .

Step 3 / 10

Add point $(4,8)$ . Mark $(1,2)$ as done.

Step 4 / 10

Add point $(7,3)$ . Annotate earlier points.

Step 5 / 10

Add two more points: $(9,7)$ and $(2,6)$ . Five points total now.

Step 6 / 10

Add points $(5,1)$ and $(8,9)$ . Highlight $(9,7)$ and $(2,6)$ as current hull candidates.

Step 7 / 10

Draw lower hull approximation line $y = 0.1x + 0.9$ . Mark hull points $(1,2)$ , $(7,3)$ , $(5,1)$ as good.

Step 8 / 10

Draw upper hull line $y = 0.5x + 4$ . Mark upper hull points as good.

Step 9 / 10

Point $(2,6)$ is interior to the hull – dim it out.

Step 10 / 10

Add origin $(0,0)$ in a late step. Does it render correctly? Is the viewBox still stable?
