- 🧠 Accepts dynamic data via `Map`
- 🎯 Built on the popular [JFreeChart](https://sourceforge.net/projects/jfreechart/) library
---
## 📁 Files
- `CustomPieChart.java` - The reusable class for generating pie charts
- `PieChartDemo.java` - A sample file showing how to use the chart
---
## 🛠 Requirements
- Java 8 or above
- JFreeChart library:
- `jfreechart-x.x.x.jar`
- `jcommon-x.x.x.jar`

## 🧪 How to Use
### 1. Add the `CustomPieChart.java` class to your project.
```java
import java.util.Map;
CustomPieChart chart = new CustomPieChart("Chart Title", yourMapData);
JPanel chartPanel = chart.getChartPanel();
yourContainerPanel.add(chartPanel);
### 2. Pass a map with your data:
```
```java
Map data = new HashMap<>();
data.put("January", 1200.0);
data.put("February", 900.0);
data.put("March", 1500.0);
```
📌 Example
```java
Map fruits = new HashMap<>();
myData.put("Apples", 25.0);
myData.put("Oranges", 20.0);
myData.put("Bananas", 40.0);
myData.put("Mangoes", 15.0);
CustomPieChart pie = new CustomPieChart("Fruit Distribution", fruits);
JPanel chartPanel = pie.getChartPanel();
myMainPanel.add(chartPanel);
```
