SVG, Scheme, and LAML

Mirror functions of SVG elements
- One-to-one correspondence between SVG elements and mirror functions in Scheme
- Generated automatically from the SVG DTD by use of LAML tools
- Contain detailed knowledge of the element contents and the attributes
- Validates the SVG document when a Scheme expression is evaluated
Main advantage
- It is possible to program abstractions on top of the native SVG elements
  - Custom tags
- It is possible to embed arbitrary computations in an SVG document
  - Evaluated at SVG generation time

The road is clear for extensions of SVG in a variety of directions

One such direction is graph drawing
