+# Examples
+This folder contains example implementations of Pygwalker across different interfaces.
+
+- [`component_demo.ipynb`](component_demo.ipynb): Creating various visualizations using Pygwalker's core components
+- [`dash_demo.py`](dash_demo.py): Integration of Pygwalker with Dash framework
+- [`gradio_demo.py`](gradio_demo.py): Using Pygwalker within Gradio applications
+- [`html_demo.py`](html_demo.py): Generating standalone HTML outputs with Pygwalker
+- [`jupyter_demo.ipynb`](jupyter_demo.ipynb): Basic Pygwalker usage in Jupyter environments
+- [`marimo_demo.py`](marimo_demo.py): Interactive data exploration using Pygwalker in Marimo notebooks
+- [`streamlit_demo.py`](streamlit_demo.py): Embedding Pygwalker visualizations in Streamlit apps
+- [`web_server_demo.py`](web_server_demo.py): Setting up Pygwalker with a web server
+
+> [!TIP]
+> To run the Marimo example, use:
+> ```shell
+> uvx marimo run --sandbox marimo_demo.py
+> ```
+> if you have [`uv`](https://docs.astral.sh/uv/) installed, or
+> ```shell
+> marimo run marimo_demo.py
+> ```
+> if you don't have uv installed (you'll need to manually install its dependencies; easier through the package manager sidebar option in marimo).
+> To edit the notebook source code, replace `run` with `edit` in the above commands.
+
+## Running examples
+Each example includes its own set of requirements and setup instructions within the file. Make sure you have Pygwalker installed:
+```shell
+pip install pygwalker
+```
+
+Additional dependencies may be required based on the specific interface you're using (e.g., streamlit, dash, gradio).
