All the greatness of [polars](https://www.pola.rs), now in Dart.

```dart

import 'package:polars/polars.dart';

final pl = PolarsWrapperImpl(dylib);

final iris = await pl.readCsv(path: 'iris.csv');

final df = await iris

  .lazy()

  .filter(pred: col('sepal_length') > 5)

  .groupby(exprs: ['species'.expr])

  .agg(exprs: [col('*').sum])

  .collect();

```
