This project was meant to fulfill creation of some astronomy charts in SVG, PNG, BMP, JPEG and probably GIF.
To fulfill requirement about SVG (and also others too) had to use very OLD
and bit bugged project called SvgNet originally developed by Ben Peterson. You can find full article about it here:
An SVG framework in C# and an SVG-GDI+ bridge
This project allowed me to use Graphics to generate SVG file and also use GDI Graphics (wrapped) thus allow to generate both raster and vector images.
A lot bugs so far, it's prealpha (fixing bugs + adding new types and features)
