```latex

\usepackage{graphicx}

...

\includegraphics[width=0.8\textwidth]{filename.png}

```

• Options: The command allows specifying dimensions (`width`, `height`), scaling (`scale`), rotation (`angle`), and clipping.

Best Practices for Including Graphics

• Use vector graphics (such as PDF, EPS, SVG) for diagrams to ensure scalability and clarity.
• Embed images with appropriate resolution; for raster images, a resolution of at least 300 dpi is recommended.
• Always specify image width relative to the text width to maintain consistency across different devices and formats.

Advanced Graphics: Creating and Managing Figures

Floating Figures and Captions

LaTeX offers the `figure` environment to position graphics as floating objects, accompanied by captions and labels for cross-referencing.

```latex

\begin{figure}[htbp]

\centering

\includegraphics[width=0.7\linewidth]{graph.pdf}

\caption{Sample graph illustrating data trends}

\label{fig:data-trend}

\end{figure}

```

• Placement specifiers: `[h]` (here), `[t]` (top), `[b]` (bottom), `[p]` (page of floats).
• Captions and Labels: Essential for referencing figures within the text.

Subfigures and Multi-Part Figures

For complex figures comprising multiple sub-figures, the `subcaption` package is invaluable.

```latex

\usepackage{subcaption}

...

\begin{figure}[htbp]

\centering

\begin{subfigure}{0.45\linewidth}

\includegraphics[width=\linewidth]{subfig1.pdf}

\caption{Subfigure 1}

\label{fig:sub1}

\end{subfigure}

\begin{subfigure}{0.45\linewidth}

\includegraphics[width=\linewidth]{subfig2.pdf}

\caption{Subfigure 2}

\label{fig:sub2}

\end{subfigure}

\caption{Comparison of subfigures}

\label{fig:comparison}

\end{figure}

```
