without having to draw a velocity-time graph?

velocity =dS/dt
accelaration = dV/dt
therefore the second derivtive of destance is acceleration.
you can work out the equation that describes the connection between time and distance and then proceed ot the second derivative wrt time.

You need to take the second time derivative of the graph. So if the distance vs time relationship is a function, you can do it via calculus. If it's just a visual graph, it will be harder to do.

It is quite difficult to do so, but a special case is easy.
Is it constant acceleration? (then the d-t graph would be a parabola ) In this case you can use the the properties of the parabola to find out the acceleration.

acceleration= the final velocity -the initial velocity divided by the time
a=v2-v1/t
