• Missing article
• Too vague, need a good value proposition here
• Shouldn't end with a period as per the Readme

I'm not sure if we need to explain the concept of a graph in this context

This should use an Admonition, see Readme

Please use standard Markdown if you want to include images. This Shortcode is only for exceptional cases where custom styling needs to be specified or if the image should have a caption.

I would generally avoid enumerations in headlines, and especially here where the content has no specific order (time/priority)

To structure the content, you should use (un)ordered lists if the child content is rather short or sub-headings if it's larger. Enumerations need to be created with markup not free-text.

• UI element labels should just be bold but not be wrapped in quote marks. Please see the reference page again: https://docs.arangodb.com/stable/components/web-interface/graphs/
• It's a dropdown menu. Maybe the term "context menu" is preferable? You can check the existing documentation, whether there is an established term already.
• Avoid using "will" etc., see https://developers.google.com/style/tense

• Use markup for ordered list
• Should be right-click (hyphen)
• Is the idea for this to be like a headline? Otherwise, I don't understand the title case

• Please don't skip headline levels. Pages should have a sound structure.
• I'm not sure about the use of emoji

Why a horizontal ruler here?

• Remove the emoji and "Note", how this remark is displayed is better left to the template of the admonition shortcode
• Unclear what "the application" refers to. Should be more specific, pointing to the current Management interface and then the Graphs section using the 2nd level navigation
• Use present tense

Leave enumerations to the content processor, i.e. no handwritten 1, 2, or 1., 2. or A, B in headlines or lists. Use unordered or ordered Markdown lists instead.

This should be an ordered list because each step is a short text, and I think it can be more concise like this:

1. In the web interface, navigate to the **Graphs** section.
2. Click the name or row of the desired graph.
3. Right-click the canvas to open the context menu.
4. Click **Create node** and select the collection to create the vertex in.
5. In the dialog that opens, you can do the following:
   - Change the target collection (**Node Type**) 
   - Optionally enter the document key for the vertex (**Node ID**).
7. Click **Create**. The new node appears on the canvas.

The same goes for creating edges, as well as deleting vertices/edges.

No quotes as I said before

Except for General Graphs, there is no space between the words, e.g. SmartGraphs. See the README

Grammar needs to be fixed, emoji removed

This seems redundant, why essentially the same description twice?

AFAICT, it doesn't necessarily show you the graph by default? For example, if I use the clear canvas option and re-open the graph visualizer, I only see the message that I need to use the Explore button to search for a node. It's important we cover the possible situations the user might find themselves in and describe all the options for selecting what is displayed to get out of nothing being displayed or displaying something specific.
