Various Information Visualization Techniques
In this section, I have tried and implemented info visualization techniques.
- A overview of image or data visualization in the corner of the screen. the overview frame remains at its size and always shows the entire diagram.
- A marker rectangle that highlights the current viewable area of the main view within the overview frame. (diagram.MouseController class).
- Made overview window arbitrarily replaceable.
- Scatterplot matrix realization for depicting multi-dimensional data.
- Then, brushing and linking techniques were implemented to mark points in a single scatterplot for being highlighted in all plots. (scatterplot.MouseController)
- Used the same dataset but now parallel coordinates display. (paracoords.View class)
- Marking technique for highlighting paths. (paracords.MouseController)
- Extension to above Movable axes in the horizontal direction.
- Graphical Fisheye View of Graphs basically an implementation of this papers Graphical Fisheye Views of Graphs (1992) Graphical Fisheye Views (1993)
- Extended the above technique for using the current mouse coordinates as the focus point while moving the pointer.
