This visualization displays hospital readmission rates across U.S. states, comparing each state’s hospital performance to national averages for various conditions like heart failure and pneumonia. The data, sourced from CMS, is loaded via `fetch` and parsed with `csvParse`. The view renders the raw parsed data as JSON text using D3’s `select` and `join` methods, with non-applicable values converted to NaN. It provides a direct, unprocessed look at the dataset’s structure and numeric fields.
