Streamlit Graphviz_chart() does not support node positions

[edsaac]

Sadly, this is an old bug/limitation of st.graphviz_chart

• Graphviz engine selection doesn't work · Issue #4089 · streamlit/streamlit · GitHub

In short, a different engine is required by graphviz to render nodes in fixed positions (check pos | Graphviz for details), however, none of them are supported by st.graphviz_chart.
