Function create_dataframe_from_map

src/memory/utils/mod.rs:579–591

Create a Polars DataFrame from a HashMap of numeric vectors. Converts analysis results stored as HashMap > into a structured DataFrame format suitable for storage in AnnData objects or further analysis. Commonly used for differential expression results, QC metrics, and other group-wise analysis outputs. ## Parameters `map` - HashMap where keys are column names and values are data v

(map: &HashMap<String, Vec<T>>)

/// - Converting analysis outputs for AnnData storage
/// - Preparing data for visualization or export
