Determine how much zooming should be applied when the mouse moves over the panel. Use the Distribution property to control the strength of the zoom effect.
Use the MinElementScale property to prevent items from getting too small.
Use the ApplyOpacity property to make elements near the mouse opaque. Items far from the mouse become more transparent, conveying an idea of distance.
With HyperPanel for WPF, you can display a large number of items in a small space. Items far from the mouse are shrunk and don’t take up much space.
