An honest note on these styles

Real graffiti lettering is hand-drawn art, built from spray-paint technique and years of style development — it can't be fully captured by swapping Unicode characters. These three styles are approximations that lean toward a graffiti feel using real character sets:

Graffiti Bubble uses rounded bubble letters, one of the most recognizable real graffiti lettering styles.

Graffiti Bold is heavy, solid bold text for a blocky tag look.

Graffiti Drip adds a dripping-paint effect using stacked Unicode marks beneath each letter.
