Abstract: Spatial Focus + Context is a well-established concept in Information Visualization, but the definition is often visualization-specific or involves multiple GUI components. This poster describes the focus-filter widget, a versatile and intuitive control element that combines dynamic data filtering and Focus + Context in 1D. The widget embeds a focus handle in a well-known range-slider for defining the location and the extent of a focus range as well as the degree of spatial distortion. We illustrate the focus-filter widget based on an application to different types of visualizations which demonstrates its portability and potential to simplify the user interface.
