This is intended for experiments with graphical layout management in Julia. It's not clear whether this has a long-term future as a standalone repository, or whether it will be integrated into other packages. For now, it's separate just to avoid breaking things in those other packages.
- Implement the "flexible core," probably based on a linear programming model such as the Auckland Layout Model. (Paper) This will support figures as vector-graphics files (svg, pdf, etc), and impose very few built-in constraints on layout. We may also want to support other optimizers besides linear programming. If they can't run quickly, they may not be suitable for real-time window resizing, but they could be used to create figures for publication.
- Find out whether the flexible core can be directly used for window resize events via callbacks (main targets might be Tk and HTML5/CSS). If not, then we probably need a raw representation that directly exposes the toolkit's manager, and then for SVG/PDF/etc we may need to mimic the toolkit's behavior in the context of the flexible core (yuck).
- Figure out how to integrate this into Compose and/or Winston.
Image1 challenges:
- Marginal axes must be aligned with the axes of the scatterplot
- The image must not look squashed or stretched along any axis
- Image is aligned with the scatterplot
- Adequate space for all labels, without overlapping other elements
There's a first draft of a working manager, based on linear programming. The test file "simple.jl" should run and produce reasonable results.
The LP interface is based on SymbolicLP.
