Need help building a custom heatmap chart for an angular project

Using this 'highcharts-angular' library (https://stackblitz.com/edit/highcharts-angular-basic-line-yah6kg?file=src%2Fapp%2Fapp.component.ts) I want to build a custom heatmap chart. My data will come from a JSON response and needs to be maped to the data series acceptedby the library(matrix(X, Y, Value)).
I attached a sample project, and I can offer more detailes with the requirements on chat.
