A **Body Temperature Graph** for menstrual cycle tracking is often used to visualize **Basal Body Temperature (BBT)** changes throughout the cycle. BBT is the lowest body temperature reached during rest and is typically measured first thing in the morning before any activity. This graph helps track ovulation and hormonal shifts, as body temperature tends to rise after ovulation due to the increase in **progesterone**.

```dart
import 'package:menstrual_cycle_widget/menstrual_cycle_widget.dart';

class MenstrualCycleGraphExample extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Body Temperature Graph'),
      ),
      body: MenstrualBodyTemperatureGraph(
        bodyTemperatureUnits: BodyTemperatureUnits.celsius,
        isShowMoreOptions: true,
        onPdfDownloadCallback: (pdfPath) async {
          // This function will be called when the user downloads an pdf
          // pdfPath contains the path to the downloaded pdf
        },
        onImageDownloadCallback: (imagePath) async {
          // This function will be called when the user downloads an image
          // imagePath contains the path to the downloaded image
        },
      ),
    );
  }
}
