I checked that option earlier. Created this scheme to avoid graphviz
package dependency
to DPDK.


commit 597f51c34826b3b12b6a1ac9d54e9160aaa49ef7
Author: Jerin Jacob <jerinj@marvell.com>
Date:   Fri Jun 23 13:06:00 2023 +0530

    doc: add inbuilt graph nodes data flow

    Added diagram to depict the data flow between inbuilt
    graph nodes.

    In order to avoid graphviz package dependency to DPDK
    documentation, manual step added to create a svg file
    from the dot file. The details for the same is documented
    in graph_inbuilt_node_flow.svg as a comment.
