I believe the answer is:

cartoonists

I'm a little stuck... Click here to teach me more about this clue!

'they draw' is the definition.
Although both the answer and 'draw' are nouns, they are not in the same form of the noun.

'it across not round' is the wordplay.
'round' indicates anagramming the letters.
'it'+'across'+'not'='itacrossnot'
'itacrossnot' is an anagram of 'CARTOONISTS'.

Can you help me to learn more?

(Another definition for cartoonists that I've seen is " Strip artists, perhaps".)

I've seen this clue in The Globe and Mail.
