## PowSyBl vs PowSyBl Single Line Diagram

PowSyBl Single Line Diagram is a component build on top of the `Network` model available in the PowSyBl Core repository responsible
for generating a [single line diagram](https://en.wikipedia.org/wiki/One-line_diagram).

The main features are:
- Node/Breaker and bus/breaker topology.
- [SVG](https://fr.wikipedia.org/wiki/Scalable_Vector_Graphics) diagram to be used in various front-end technologies.
- Voltage level, substation and zone diagrams.
- Highly customizable rendering using equipment component libraries, CSS and configurable labels (position and content).
- Multiple layout modes: fully automatic, semi-automatic (using relative positions for busbar sections and feeders), CGMES DL.

*A guide to generate this diagram is available [here](https://www.powsybl.org/pages/documentation/developer/api_guide/single-line-diagram/svg-writing.html).*

## Getting started

To generate a SVG single line diagram from a voltage level, we first need to add a Maven dependency for the `Network` model
and additionally for this example two other ones: one for the `Network` test case, one for simple logging capabilities:

```xml
<dependency>
<groupId>com.powsybl</groupId>
<artifactId>powsybl-iidm-impl</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>com.powsybl</groupId>
<artifactId>powsybl-iidm-test</artifactId>
<version>5.0.0</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.22</version>
</dependency>
```

We can now load a node/breaker test `Network`:
```java
Network network = FictitiousSwitchFactory.create();
```

After adding the single line diagram core module dependency:
```xml
<dependency>
<groupId>com.powsybl</groupId>
<artifactId>powsybl-single-line-diagram-core</artifactId>
<version>3.0.0</version>
</dependency>
```

We can now generate a SVG for the voltage level `N` with the following simple unique code line:
```java
SingleLineDiagram.draw(network, "N", "/tmp/n.svg");
```

We obtain the SVG below.

![Diagram demo](.github/example_n.svg)

Note that a JSON file named `n_metadata.json` is also generated in the same folder, containing all the metadata needed to interact with the diagram.
**PowSyBl diagram allows users to generate customizable network graph diagrams (denominated network-area diagrams in PowSyBl) and single-line diagrams.**

## PowSyBl vs PowSyBl Network Area Diagram

A network area diagram emphasizes the electrical structure of the network, and may differ substantially from the network physical geography.
It displays the graph whose nodes are the network voltage levels, and whose edges are the lines and transformers between those voltage levels.
