This example demonstrates usage of d3-component to create a spinner component, and render it conditionally while something is loading. After loading finishes, the spinner goes away and is replaced by another component.
How often have you seen a data visualization show nothing but a blank screen while the data is loading? Showing a spinner with D3 and hiding it after data is loaded is not as easy as it seems. Here’s a solution for doing this, feel free to use it in your projects!
This demonstrates the following patterns supported by d3-component:
- Use of local state and lifecycle hooks (spinner timer).
- Composition of components with conditional rendering (app component).
