I have been working on a CAD JavaScript library that can render hi-def spatial diagrams using HTML only. I set out to code this library because as it appears with the algorithm I devised very long time ago spacial diagrams cost quite little terms of memory. The library is few kilobytes and doesn't use 3rd party resources. Its GUI is still basic but will be complimented over time.
