Module data 

Data ingestion and columnar storage layer.

This module is intentionally backend-agnostic:

• DataSource is a trait for host applications to provide numeric columns.
• DataTable is an internal normalized representation used by the editor.
• CSV/TXT parsing utilities build DataTable from files.

Structs

ColumnData

One numeric column with a stable display name.

DataTable

In-memory normalized table used by plotting logic.

Traits

DataSource

Generic data-provider contract for embedding this crate into host apps.
