S1 removed bayesian networks as a parent node of "The 3 Junctions in Causal Diagrams". They stated that Bayesian Networks are not a prerequisite to understand the causal junctions which is why it shouldn't be a parent node.

The teacher of the course updated the formatting of the content to incorporate MathJax. In their proposal it was stated the purpose was to improve the content.

S13 edited the title and explanation of the 3 causal junctions to remove references of Bayesian networks from the definition. While causal diagrams are similar to bayesian networks in structure and composition, it would be incorrect to label the junctions in bayesian networks as causal. This edit was made after S13 had a conversation with the teacher of the course, who suggested to make this change.
