Focus+Context

A visualization interaction paradigm that integrates a detailed focus region and its surrounding context into a single unified view, rather than separating them. Techniques include fisheye views, semantic zooming, and lenses that distort or overlay content so users can see fine detail while retaining orientation. In accessibility, focus+context approaches can reduce the panning and zooming burden for low-vision users by bringing contextual elements (axes, legend, grid lines) close to the point of interest.
