The biggest problem with redesigns, however, is their removal of context. Design is compromise. Anyone who’s ever designed a logo, made a movie, or built a house, knows that the final product reflects a series of mostly hidden goals and constraints. To redesign without knowing these constraints — the client insisted on pink! the lead actor broke his ankle! the zoning board was insane! — is, in some sense, unfair. — Fernanda Viégas & Martin Wattenberg, Design and Redesign in Data Visualization
