The text provides a detailed guide on creating interactive dashboards using Grafana, an open-source visualization tool, to enhance usability for non-technical stakeholders. It highlights the common issue of static dashboards that require engineers to make code changes for detailed insights and proposes a solution through Grafana's variables feature. By using Grafana's UI, users can incorporate interactive elements like "pickers" or filters, enabling stakeholders to manipulate data without altering the underlying SQL queries. The example of monitoring live bus locations in New York City is used to illustrate the process of creating a variable that controls the visualization of different bus routes. The guide explains how to define a SQL query that generates a variable and modify the graph query to incorporate this variable, allowing users to select from multiple options or all routes, resulting in a dynamic visual representation that updates based on user selections. The guide concludes with additional resources for building Grafana dashboards, offering comprehensive tutorials and tips for visualizing data effectively.
