Try to check out my solution on github: OrgChart.svg
The chart is fully rendered in SVG. Supports tip-opver / stacking strategy which is probably the best known solution to create good organisational charts. I would be very happy if it helps someone. It is based on snap.svg.
- custom styling using own SVG fragments designed e.g. in Adobe Illustrator
- tip-over / stacking to handle huge amount of nodes in one level
- it's open source, you can use it for free in any project!
