Custom interactive visualizations

If you want to build bespoke, code-first, programmatically interactive visualizations for web dashboards, I’d look beyond traditional drag-and-drop BI tools toward BI-as-code platforms, developer-oriented data-app frameworks, and embeddable analytics platforms.

The most important distinction is whether you want to write the visualization itself in code, or use code to define a dashboard made from existing charts and components.

Best options to evaluate

Shortlist based on customization, interactivity, developer workflow, and dashboard capabilities.
