Feature Description

Hi,

I love the ability to use Mermaid directly from markdown, but there is one very useful feature missing: the ability to use the "elk" layout/renderer.

I tried both the layout and defaultRenderer configuration options (still not sure what's the difference), and passing those via front-matter and directives, but none seems to work.

Code:

---
config:
  layout: elk
  flowchart:
    defaultRenderer: elk
---
%%{ init: { "layout": "elk", "flowchart": { "defaultRenderer": "elk" } } }%%
flowchart TB
  A --> B
  A --> C --> B
