Stroom Visualisations Development is a toolkit for building and testing custom data charts that work inside Stroom, a data analytics platform. Stroom lets users add their own JavaScript-based visualizations at runtime, and this project provides a sandbox where developers can create, tweak, and test those visualizations without needing to deploy or even run Stroom itself. The project works by generating random test data for each visualization type, so you can see how a chart behaves as if it were live. You pick a visualization from a dropdown, adjust settings like whether axes are visible or whether color scales sync across grid cells, and click update to see the result. The visualizations share a common look and feel and follow a consistent API, meaning they respond to data changes in real time and resize to fit their container. A key concept is the "gridded" visualization, which lets you display multiple groups of data side by side in a grid, each cell showing one slice of the data. This would be used by analysts or developers working within a Stroom environment who need custom charts beyond the defaults, or by teams building dashboards that visualize large datasets across multiple grouping levels. For example, if you are monitoring network traffic and want to see activity broken down by hour and day across different regions, the heat map or bar chart visualizations here would let you display all those groups on one screen. The visualizations are built to be portable. While designed for Stroom, they are not tightly coupled to it, so other applications can use them as long as they provide data in the expected format. The README notes that some visualizations are still work in progress, and the test harness currently works best in Google Chrome.
