Help:Graph

Help:Graph

The Help:Graph page is a comprehensive guide for users who wish to create and manipulate graphs within the MediaWiki environment. This feature is particularly useful for visualizing data in a clear and concise manner, making it an invaluable tool for educators, researchers, and students alike.

Overview

Graphs in MediaWiki are created using the Extension:Graph extension, which allows users to embed complex and interactive graphs directly into wiki pages. This extension leverages the power of the Vega and Vega-Lite visualization grammars, enabling the creation of a wide range of graph types, from simple bar charts to intricate network diagrams.

Getting Started

To begin using graphs in your MediaWiki pages, ensure that the Extension:Graph is installed and enabled on your wiki. Once the extension is active, you can start embedding graphs using the ```

This example creates a simple bar chart with embedded data. The graph is defined using JSON syntax, specifying the data, type of graph (mark), and how the data is encoded into visual elements.

Advanced Features

Interactivity

Graphs can be made interactive by adding event listeners and dynamic data updates. This is particularly useful for creating dashboards or educational tools where users can explore data in real-time.

Data Sources

Data for graphs can be embedded directly within the graph definition or loaded from external sources such as CSV files or APIs. This flexibility allows for the integration of live data feeds into your wiki pages.

Customization

The appearance and behavior of graphs can be extensively customized. Users can modify colors, scales, axes, and legends to suit their specific needs. This is achieved by altering the JSON configuration within the <graph> tag.

Troubleshooting

If you encounter issues with your graphs, ensure that the JSON syntax is correct and that the Extension:Graph is properly installed. Common errors include missing commas, incorrect field names, or unsupported graph types.
