I am currently working on algorithms for placement of captions on charts. I am testing and implementing some methods. One of them works by sampling the desired area of placement in a circle around the origin of the caption.
A premature version of this is already implemented into Smrender since one of the early releases.
Now I am working on improvements and accidentally discovered that my software is able to create a cool panorama chart out of sea chart. This is standing on a point somewhere in the chart and having a panoramic sight to all directions.
The image at the top of this posting is generated at the summit of Kornat island in Croatia. On the left is the direction to the East, going South, then West, North, and East again on the right edge of the image.
