I'm not that keen on either guitar or violin as jazz instruments. I can't explain why this is. They've just never struck me as fitting the idiom as well as piano, trumpet, sax, trombone, clarinet. However, this prejudice is totally overcome by Django Reinhardt, whose music I love. As it says here:
He would spin joyous, arcing, marvelously inflected solos above the thrumming base of two rhythm guitars and a bass, with [Stéphane] Grappelli's elegantly gliding violin serving as the perfect foil.And that's as much as needs to be said. I'm suggesting the Verve compilation Jazz Masters 38 (1938-53 - 49 minutes) for your collection, though there's plenty else. Three YouTube clips.
