AI Drawing Prompt Reference

Draw two basis vectors in a 2D coordinate system and show how they generate points on the axes through linear combinations. Then, draw two sets of parallel lines using these basis vectors to form a grid. Find the intersection points of these lines and connect them to the origin to draw transformed coordinate axes. Finally, draw a vector and show its representation in both the original and new coordinate systems to visualize the effect of basis transformation.
