Morse Code

• International Morse Code

\begin{tikzcd} O & M \ar[l,"-"'] \ar[d, "\cdot"] & T \ar[l,"-"'] \ar[ddd, "\cdot"] & \mathrm{Start} \ar[r, "\cdot"] \ar[l,"-"'] & E \ar[r, "\cdot"] \ar[ddd, "-"] & I \ar[r, "\cdot"] \ar[d, "-"] & S \ar[r, "\cdot"] \ar[d, "-"] & H \\ Q & G \ar[l,"-"'] \ar[d, "\cdot"] & & & & U \ar[d, yellow, "\cdot"] & V & \\ & Z & & & & F & & \\ Y & K \ar[l,"-"'] \ar[d, "\cdot"] & N \ar[l,"-"'] \ar[dd, "\cdot"] & & A \ar[r, "\cdot"] \ar[dd, "-"] & R \ar[r, "\cdot"] & L & \\ & C & & & & & & \\ & X & D \ar[l, "-"'] \ar[d, "\cdot"] & & W \ar[r, "\cdot"] \ar[d, "-"] & P & & \\ & & B & & J & & & \\ \end{tikzcd}

The graph is inspired by similar shaped product.
