DotExporter

Exports flatgraph to graphviz dot/gv file

Note: GraphML doesn't natively support list property types, so we fake it by encoding it as a ; delimited string. If you import this into a different database, you'll need to parse that separately.

Export rules for dot format as per https: //github.com/joernio/joern/issues/5158 1) If the attribute value contains special characters such as spaces,<,>,=, etc., it must be enclosed in double quotation marks. Otherwise, it will cause syntax errors. 2) Graphviz requires that the node ID must be a valid identifier. If the node ID is a pure number (such as 120259084301), it needs to be enclosed in double quotation marks, otherwise it will be mistaken for an integer constant. 3) The attribute value contains special characters such as(such as CODE=""), which need to be enclosed in quotation marks or escaped in some cases. 4) In Graphviz's. dot file, it is best to use semicolons for each node definition, edge definition, and attribute definition; ending. Your file is missing semicolons.
