Given a s-expression and a filename, this routine creates a DOT-file that can be used to generate a visualization of the s-expression data structure. This is useful for debugging to ensure that the structure is correct and follows what was expected by the programmer. Non-trivial s-expressions can yield very large visualizations though. Sometimes it is more practical to visualize a portion of the structure if one knows where a bug is likely to occur.
|sx ||S-expression data structure to create a DOT file based on. |
|fname ||Filename of the DOT file to emit. |
