Current behavior

When creating "tall" mermaid graphs, the graph area is not resized in height, resulting in unreadable text, both in preview and in output

Expected behavior

The graph area should be resizable, to allow creation of readable graphs. One option could be, to allow user specified dimensions for the created graph area.

Steps to reproduce

1. create a new note
2. Insert:

\`\`\`mermaid
graph TB
    c1-->c2
    c2-->c3
    c3-->c4
    c4-->c5
    c5-->c6

3. Observe the resulting output:
