Building SVG Charts with Contex in Phoenix LiveView

Raw data is only valuable when your users can easily digest it. Standard charting libraries often rely heavily on complex client-side JavaScript, but Phoenix LiveView offers a more efficient, server-rendered alternative. In this text-only course, you will learn how to generate lightweight, dynamic SVG charts directly on the server using the Elixir Contex library. By understanding how to integrate these charts into Phoenix LiveView, you will be able to build fast, interactive dashboards that update in real-time without the overhead of heavy JavaScript frameworks. What you'll learn: - Understand the core concepts of server-side SVG rendering and how Contex structures chart data - Configure different chart types including bar charts, point plots, and sparklines - Integrate Contex datasets and charts natively within Phoenix LiveView lifecycle events - Apply modern Phoenix LiveView component patterns to make your SVG charts reusable - Practice updating charts dynamically in response to real-time database changes or user interactions - Optimize SVG rendering performance for high-frequency data updates You will start with the absolute basics of SVG structures and Contex dataset definitions before moving on to rendering step-by-step chart examples. The written material guides you through building a complete, reactive dashboard using text explanations and clear code snippets. This course is designed for web developers new to data visualization in Elixir. A basic familiarity with Phoenix is helpful, but no prior experience with Contex or SVG rendering is required.
