Sure, this is already supported via the Visual Watch plugins. You can use the Debug->Visual Watch command to display arrays as graphs or images.
You can also create your own Visual Watch plugins to cover the cases not supported directly. E.g. you can fork our ImageWatch plugin and replace the version in “C:\Program Files (x86)\Sysprogs\VisualGDB\VisualWatchProviders” file, or place it under a different name to the same directory, or under %LOCALAPPDATA%\VisualGDB\LiveWatchProviders.
