Hello

I’d like to know the syntaxe for Mac to create executable with graphics

I have the graphic window with

```auto
$ utop
#require "graphics" ;;
Graphics.open_graph "";;

```

but with compile syntaxe like

```auto
% ocamlc graphics.cma test_graph.ml

```

I get

```auto
**File "test_graph.ml", line 18, characters 0-19** :
18 | Graphics.open_graph "";;

**^^^^^^^^^^^^^^^^^^^**

**Error** : Unbound module Graphics

```

How to do ?

The program is

```auto
Graphics.open_graph "";;

```
