Grafana 7.0 introduces a new React-based plugin platform, simplifying the creation of custom plugins, such as a scatter plot visualization. This guide demonstrates building a scatter plot panel plugin using React and D3.js, emphasizing the use of SVG for rendering and D3 for data transformations. The tutorial details the setup process using the grafana-toolkit, configuring the development environment with tools like Docker and NodeJS, and developing the plugin with JavaScript and TypeScript. It covers creating a basic scatter plot by generating data points, scaling them with D3, and rendering them as SVG elements. The tutorial also explains adding axes to enhance the visualization and adjusting margins to properly position elements within the chart. Although the guide provides a basic scatter plot using randomly generated data, it hints at future enhancements, such as integrating real data sources and offering user configurability.
