Detailed Description

Modal dialog that lets the user pick a CSV or JSON file and map its columns to graph node/edge identifiers before importing attributes.

Usage:

DialogImportAttributes dlg(DialogImportAttributes::Scope::Nodes,
                           true,   // isCSV
                           parent);
if (dlg.exec() == QDialog::Accepted) {
    graph->vertexAttributesImport(dlg.parsedTable().headers,
                                  dlg.parsedTable().rows,
                                  dlg.idColumn(),
                                  dlg.matchByLabel());
}
