How is the line used in the painting at the Moulin Rouge?

In Henri de Toulouse-Lautrec's painting "At the Moulin Rouge," line is used to create dynamic movement and guide the viewer's eye through the composition. The bold, swirling lines of the figures and the flowing curves of the dancers’ costumes convey a sense of energy and excitement characteristic of the bustling Parisian nightlife. Additionally, the use of contour lines helps to define the shapes of the subjects, while also emphasizing their interactions, contributing to the overall vibrancy of the scene.
