    ### 📈 Improvements & Future Iterations
    * **Demographic Gaps:** Future nodes could visualize specific survival disparities in men vs women and different age demographics.
    * **Cost-Stage Correlation:** Visualizing how economic burden shifts from "one-time" surgical costs in early stages to "continuous" high-cost in metastatic stages.
    * **Inclusive Data:** Ensuring rare types like Nasopharyngeal have the same depth of data as common types like Lung or Skin.
