A method, and associated systems and computer programs, for generating a visual display of graphical data comprises retrieving and displaying an initial approximate visual representation of the graphical data, progressively retrieving and displaying the graphical data, the graphical data being processed from source data representing a plurality of graphical elements, for full quality on-screen rendering. While the graphical data is being retrieved and/or the source data is being processed for full quality on-screen rendering, the display is progressively updated by blending the approximate representation with elements of the graphical data that have been retrieved for full quality on-screen rendering. The blending presents the approximate representation as a partially transparent overlay on top of the retrieved elements of graphical data.
