We study the uniform random graph $mathsf{C}_n$ with $n$ vertices drawn from a subcritical class of connected graphs. Our main result is that the rescaled graph $mathsf{C}_n / sqrt{n}$ converges to the Brownian Continuum Random Tree $mathcal{T}_{mathsf{e}}$ multiplied by a constant scaling factor that depends on the class under consideration. In addition, we provide subgaussian tail bounds for the diameter $ ext{D}(mathsf{C}_n)$ and height $ ext{H}(mathsf{C}_n^ullet)$ of the rooted random graph $mathsf{C}_n^ullet$. We give analytic expressions for the scaling factor of several classes, including for example the prominent class of outerplanar graphs. Our methods also enable us to study first passage percolation on $mathsf{C}_n$, where we show the convergence to $mathcal{T}_{mathsf{e}}$ under an appropriate rescaling.
