💡 What: Optimized the Treeview visualization by constructing a partial D3 hierarchy that includes only visible nodes before calculating the layout.
🎯 Why: The original implementation passed the entire tree (including collapsed nodes) to
d3.tree, causing significant performance overhead for large datasets where most nodes were hidden.d3.treeiterates over all nodes in the hierarchy.📊 Impact: Reduces layout calculation time significantly for large trees with collapsed branches. Complexity reduces from O(Total Nodes) to O(Visible Nodes).
🔬 Measurement: Added a new test suite
src/visualizations/treeview/__tests__/Treeview.spec.tswhich verifies that the component still renders and handles interactions correctly. The optimization is algorithmic.PR created automatically by Jules for task 7304065728329940854 started by @pverscha
