The Grid:
A graph, with each cell representing a node. Each cell is connected to adjacent cells horizontally and vertically by invisible edges that (by default) cost 1 to traverse.

Weights/Walls:
Drag or click anywhere on the grid to place or remove weights or walls. Use the dropdown to toggle between the two.
- Weighted cells: These cells have edges that cost 10 to traverse.
- Walled cells: These cells do not have edges connecting them to adjacent cells.

Simulation Speed:
Use the dropdown to toggle between simulation speeds. "Instant" skips the algorithm steps and immediately draws the path.

Themes:
Use the rightmost dropdown to toggle between color themes for the simulation.
