### Understanding Graphs: Weighted Graph Example

Welcome to our educational page dedicated to understanding graphs, specifically weighted graphs. In this example, we will explore the structure and components of a weighted graph, which is commonly used in fields such as computer science, networking, and transportation planning.

#### Image Description

The image above displays a weighted graph. A weighted graph is a type of mathematical graph in which each edge (connection between two vertices, or points) has a numerical value (weight) associated with it. These weights can represent various things, such as distances, costs, or times.

#### Key Components of the Weighted Graph:

- **Vertices (Nodes):** Points where edges meet. In this graph, the vertices are labeled as A, B, C, D, and E.
- **Edges (Connections):** The connections between vertices. Each edge is represented by a line connecting two vertices.
- **Weights:** Numerical values assigned to the edges. These values are usually written along the edges. In this graph, the weights range from 2 to 9.

#### Detailed Explanation of the Graph:

1. **Vertices:**
   - A, B, C, D, and E are the vertices of the graph.

2. **Edges and Weights:**
   - Edge AB has a weight of 2.
   - Edge AC has a weight of 4.
   - Edge AD has a weight of 8.
   - Edge AE has a weight of 5.
   - Edge BC has a weight of 7.
   - Edge BD has a weight of 5.
   - Edge BE has a weight of 6.
   - Edge CD has a weight of 3.
   - Edge CE has a weight of 2.
   - Edge DE has a weight of 9.

#### Applications:

Weighted graphs are used in various applications:

- **Network Design:** Optimizing paths for minimal cost or maximum efficiency.
- **Transportation:** Planning routes and understanding the shortest or safest paths.
- **Project Management:** Determining critical paths in task schedules.

Understanding weighted graphs is crucial for solving real-world problems that require efficient decision-making based on multiple factors. This example helps illustrate the basic components and usage of weighted graphs.
