These integration guides are not official documentation and the Strapi Support Team will not provide assistance with them.
You can use the Chartbrew plugin for Strapi to easily connect the two platforms together. The plugin also comes with a dedicated Chartbrew tab in the Admin dashboard where you can visualize your Strapi data with a click of a button. You can also use Chartbrew's UI for more advanced visualization editing and all charts can then be visible back in the Admin dashboard.
