Aytham in Tamil is a third dimensional phenomenon,
1/ Vowels
2/ Consonants
3/ Aytham
(Aytham is a modulator. Examples, does glotalising modulation, "q"ised modulation (not q), "h"ised modulation (not h), etc..) (Aytham also borders on the behaviour of both Vowels and consonants.)

In the orthodox Tamil, as taught and learnt in the native user's land, there is no such letter named as 'visarga'. But it has a letter taught as 'Aytham' which is never referred by the word 'visarga' Only in Unicode they are referring 'Aytham' by a non-Tamil word 'visarga'.
There is a clear glyph difference between Tamil Aytham which is with three dots in triangular formation (pyramid) while the devanagari visarga have only two dots i.e.one vertically above the other nearly same as the punctuation mark - semi colon
When there is no such letter as two dot visarga in Tamil, if any one uses it for any semantics in Tamil it may be in his/her own personnel whims and may be treated as a bad practice. If the letter in use is Tamil 'Aytham' then they would have marked by a three dot glyph for canonical correctness.
The 'Aytham is sometimes a misunderstood letter even by some Tamils when they try to represent it in transliteration by 'q' Aytham does not have any phonetic proximity to /q/ at all, while it is almost same as to the phoneme represented by a the ligature 'æ' = 'a' as in bad, cat, dab, fat, man, pat, rack, sap etc. That is the reason why it is referred as 'Tamil Letter Visarga' in Unicode.
The phonetics of Aytham is precisely defined in standard Tamil grammar as 'Nannuul' as 'Aytak kiTan2 talai angkA muyaRcci' ( transliterated Tamil written in IITS Cologn scheme) i.e. "Articulation of Aytham has its origin from the upper part in exhaling just by opening of the mouth" ( by slightly tilting head upward while exhaling.) The phonetics of Aytham is even shown by an example as 'kæcu' is very near to 'kaicu' in articulation in the commentary of the same cUtram of the quoted Grammar
( kæcu is an antique coin of smaller denomination. It was else where shown as a link with the word 'cash')
We can say that Tamil Aytham is a short form of the compound vowel : 'a' + 'e' = æ because timing of iits articulation is well demarcated in Tamil grammars that it is a letter with half 'nodi' (compare it from normal vowels are of one nodi while long vowels are of two nodi-s) ( two other compound vowels with two nodi-s being 'a'+'i' = 'ai' and 'a'+'u' = 'au' )
Graphically it can be shown the app.phonetics of Æ as in the drawing below
If we consider both /A/ & /E/ are at axes in quadrature to each other, then the /Æ/ is born when one try to pronounce both /A/ & /E/ at the same instance. More precisely the Æ has equal bearings in two axes as /A/ & /E/ ( I could not shape a perfect 45 degrees slant line in my attempt of producing an image made from typed characters)
/E/ /Æ/
