An official document or charter, particularly one in Latin; also a map or chart.
From Latin charta meaning 'paper' or 'document,' derived from Greek khartēs, ultimately from Egyptian origins. The word evolved to mean any official written document.
Charta is why we have 'charter,' 'chart,' and 'charter school' in English—all springing from this ancient word for 'paper' that became synonymous with official authority.
