9.9.1 Parallel Keyword

Specifying the keyword parallel in front of an element will make the rest of the chart be drawn in parallel with it. To be more precise the effect only lasts till the end of the scope, so elements after the next closing brace will be drawn sequentially under48.

You can place parallel in front of really any element, including entity definitions or even series of parallel blocks. You can even combine several elements using braces.

This is how this works exactly: first, the element marked with parallel is placed. Then the rest of the elements in the scope are placed below it and are moved as one block up at most to the top of the element marked with parallel. The move stops if any element in the block being moved bumps into an already placed element, thus overlaps are avoided.
