An Ordinary Differential Equation (ODE) defines a vector field. Solutions flow along this field. We visualize this with a Phase Portrait.
Phase Space: A plot where axes are state variables (e.g., Position $x$ vs Velocity
$v$).
Vector Field: At each point, an arrow points where the state will go next.
Instructions: Select a system. Click on the canvas to spawn a trajectory starting from that state.
