### Custom Configure Execution

Source: https://graphviz.org/_print/doc/build.html

Example of running configure with specific paths for dependencies and installation prefixes.

```bash
./configure  --prefix=$HOME/arch/sgi.mips3 \
	--with-freetypeincludedir=$HOME/arch/$ARCH/include/freetype2 \
	--with-freetypelibdir=$HOME/arch/$ARCH/lib \
	--with-tcl=/usr/common/tcl8.3.3
```

--------------------------------

### Build and Install Graphviz (MinGW)

Source: https://graphviz.org/_print/doc/build.html

Compile and install Graphviz after configuring and modifying Makefiles.

```bash
make  # builds most of "lib" (see Makefile changes), cmd/dot and cmd/tools - stops on cmd/gvpr
make install

```

--------------------------------

### Example Configure with Custom Paths

Source: https://graphviz.org/doc/build.html

This example demonstrates how to use the configure script with custom include and library directories, and specifies a Tcl version. Adjust paths to match your system.

```bash
./configure  --prefix=$HOME/arch/sgi.mips3 \
	--with-freetypeincludedir=$HOME/arch/$ARCH/include/freetype2 \
	--with-freetypelibdir=$HOME/arch/$ARCH/lib \
	--with-tcl=/usr/common/tcl8.3.3

```

### Install Graphviz via Windows Package Manager

Source: https://graphviz.org/download

Use the winget command to install Graphviz on Windows.

```bash
winget install graphviz
```

--------------------------------

### Example Plain-Ext Output

Source: https://graphviz.org/docs/outputs/plain

This is an example of the output generated by `dot -Tplain-ext` for a simple graph, showing port names for edges when applicable.

```bash
$ echo 'digraph { a->b }' | dot -Tplain-ext
graph 1 0.75 1.5
node a 0.375 1.25 0.75 0.5 a solid ellipse black lightgrey
node b 0.375 0.25 0.75 0.5 b solid ellipse black lightgrey
edge a b 4 0.375 0.99579 0.375 0.88865 0.375 0.7599 0.375 0.64045 solid black
stop

```

```bash
$ dot -Tsvg input.dot
```

--------------------------------

### Build and Install Graphviz

Source: https://graphviz.org/doc/winbuild.html

Compile and install Graphviz after running configure. This command builds most of the library, command-line tools, and stops at 'cmd/gvpr'.

```makefile
make  # builds most of "lib" (see Makefile changes), cmd/dot and cmd/tools - stops on cmd/gvpr
```

```makefile
make install
```

--------------------------------

### Check Version Information with -V

Source: https://graphviz.org/_print/documentation
