When using long names for `places` or `transitions`, currently this will not be properly rendered it via the `GraphvizDumper`, see below.

By setting the default to `fixedsize=false` it will autofit the label in the rendering.

This will also solve the warning when running the `dump` command:
`Warning: node 'place_08b79deda74a924c3babb9b1d0f3e4eed9320989', graph 'workflow' size too small for label`
