Looks like you are using Highcharts and chart.js ... and Leaflet for the maps? Since you are using React, Airbnb's Visx [0] might be a very good charting solution so you have a unified chart library with flexibility to meet customer demands in the future. Also, you will find customers demanding mobile access to their data and dashboards soon enough and having a system that is built on low level d3.js api's it will be easy to implement the charts using the same strategy visx does in React Native.
That's my two cents.
