These components represent a pattern that you can use when working as a part of a Hybrid Team. When working with Data Scientists you'll need to ensure that you communicate as often as you possibly can with that team. They will be doing hard work using Plotly to ensure that the data they're working with is charted out in a visually appealing way, however you'll need to work with them to integrate their work into the app.
The RenderDataViz.js file demonstrates how you can pull in data from an external API, set that data on state, and then pass that data down to a <Plot /> component. In this case, the URL for the plot component is the only prop that will be needed to send off the API call and subsequently mount the Plot components w/ the appropriate data. Be sure to handle your errors nicely.
