Tree diagram from csv using v4
This tree diagram visualizes hierarchical data loaded from a CSV file, displaying nodes as white circles with steel-blue outlines connected by curved gray links. The visualization uses d3.v4's `d3.tree` layout, `d3.stratify` to convert flat parent-child records into a hierarchy, and `d3.hierarchy` to map the structure. Text labels appear beside each node, positioned differently for internal versus leaf nodes. The SVG rendering includes CSS styling for node circles, text shadows, and link strokes, following the D3 Tips and Tricks book example.
