I am new to TypeDB Studio. I have created a schema and committed it to my database. Is there a way to visualize the graph for the schema in Studio, before adding any data? I am working on the latest version (2.17.0) for macOS. Alternatively, is there any other compatible tool or client that can be used to visualize the schema?

Thanks,  
Aparna

Sure! Use the following query:

```auto
match $x sub thing;

```

This will provide you with a graph of the schema.

Somehow this doesn’t work for me.

I’ve created a clean new database, wrote the Quickstart schema example to database and tried out your query. I get this error:

```auto
## Error> [TQL03] TypeQL Error: There is a syntax error at line 1:
match $x sub thing;
                  ^
no viable alternative at input 'match $x sub thing;'

```

If I add the instance data from the quickstart as well and try out some basic example queries, that **does** work. But then still I cannot query the schema it seems.

Can anyone help me out? (Perhaps I should create a new topic)

Thanks

Hi @bartkl  
Since the introduction of `fetch`, TypeQL requires a match statement to be followed by either a `get` or a `fetch`.

Here, you should just need to add a `get`

```auto
match $x sub thing; get;

```

Ah, thanks, that works 🙂. I’m new to the framework, and very excited for it!

Hi all, how does the query look like for TypeDB 3? `match $x sub thing; get;` does not work any more? Thank you!

Should be `match $x sub thing;` without the get.  
Note that the 3.x versions of studio do not have visualisation

@krishnan we don’t have `thing` as a type anymore in 3.0!

If you want entity types:

```auto
match entity $t;

```

relations/attribute follow: `match relation $t` or `match attribute $a`

Oopsies. I forgot we did that.  
`match $t sub $_;` might also work?

Great, that works indeed! Thank you very much.  
the `$_` is not documented anywhere yet, right? And are there plans to add the visualisation back again? It was really appealing and convenient in v2. Thank you again!

Might not be documented. It’s just a variable without a name. Now that I think about it, The best way to do this might be to write  
`match $t sub $t;`

</div>

`$t sub $_` will work only if there is an existing subtyping for a type. However, it won’t match `email`s and `name`s (`name`s are abstract, so whatever, but we do care about emails) in this schema:

```auto
define 
  attribute name @abstract, value string;
  attribute first-name sub name;
  attribute email value string;

```

There is no short equivalent of `isa thing` anymore, because all types are split to kinds more explicitly. @joshua gave the correct answer. In general, it’s like

```auto
match
  { entity $t; } or { relation $t; } or { attribute $t; }; $x isa $t;

```

This might be blocked by multiple rebindings of `$t` in 3.0, but should be available in 3.1 (RC is coming out this week).

I don’t think this is true because a `sub` matches the type itself. It’s like the difference between `sub*` instead of `sub+` in regex.

It worked fine for me here:

```auto
query-schema::read> match $sub sub $sup;
                    
Finished validation and compilation...
Streaming answers...

   ----------
    $sub | type parent
    $sup | type parent
   ----------

```

You’re actually right. I guess I got too deep into the Concept layer in the recent weeks, my bad.

(so actually that does not work ;))

```auto

Ah, thanks for reporting.

URGENT!! Thanks for sharing $\_.  
How can I visualize graph now in TypeDB Studio? It has been discontinued lately in V3+.
