Fully working example is stored in [libs/next_gen_ui_langgraph/readme_example.py](https://github.com/RedHat-UX/next-gen-ui-agent/blob/main/libs/next_gen_ui_langgraph/readme_example.py) and you can try it right away.
## 1. Install dependencies
Install NextGen UI agent packages `next-gen-ui-agent`, `next-gen-ui-langgraph` and NextGenUI web component rendering `next_gen_ui_rhds_renderer`:
```sh
pip install -U next-gen-ui-agent next-gen-ui-langgraph next_gen_ui_rhds_renderer
```
!!! note
It's common to create a virtual environment first in your project.
```sh
python3 -m venv .venv && source .venv/bin/activate
```
## 2. Example code
```py
{%
include-markdown "../../libs/next_gen_ui_langgraph/readme_example.py"
%}
```
## 3. Run example
Run example to get JSON representation of the Next Gen UI Component.
```sh
python readme_example.py
```
JSON component:
```js
{
'component': 'video-player',
'id': 'call_zomga3r3',
'title': 'Toy Story Trailer',
'video': 'https://www.youtube.com/embed/v-PjgYDrg70',
'video_img': 'https://img.youtube.com/vi/v-PjgYDrg70/maxresdefault.jpg'
}
```
## 4. Try web component rendering
Change variable `component_system` to `rhds` and rerun. You'll get web component rendering.
