As a new user to Pygal, I want to understand how to install the library and then find a basic example for creating a bar chart. Please provide the installation command for Pygal, and a minimal Python code snippet that creates and renders a simple bar chart to an SVG file. Additionally, provide the name of one built-in style that can be used with Pygal charts.
Navigate to 'https://www.pygal.org/en/stable/'. Click on the 'Installing' link. Identify and extract the command to install Pygal. Navigate to the 'Documentation' section. From the 'Documentation' section, navigate to 'Chart types'. Click on the 'Bar' chart type link. Extract a minimal Python code snippet that creates and renders a basic bar chart to an SVG file. Navigate back to the 'Documentation' section and then to the 'Styles' section. Identify and extract the name of one built-in style. Synthesize the installation command, the bar chart code snippet, and the name of the built-in style.
The agent successfully navigates to the Pygal homepage. The agent successfully navigates to the 'Installing' page. The agent identifies the installation command as `pip install pygal`. The agent successfully navigates to the 'Documentation' page and then to the 'Bar' chart type page. The agent extracts a Python code snippet for a bar chart that includes `import pygal`, `chart = pygal.Bar()`, `chart.add(...)`, and `chart.render_to_file('bar_chart.svg')` or similar rendering to SVG. The agent successfully navigates to the 'Styles' page and identifies at least one built-in style (e.g., 'DarkStyle', 'LightStyle', 'CleanStyle', 'NeonStyle', 'BlueStyle', 'DarkGreenBlueStyle', 'RedBlueStyle', 'TurquoiseStyle', 'SolidStyle', 'DefaultStyle'). The agent provides the installation command, the bar chart code snippet, and the name of a built-in style in its final answer.
