SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
First I recommend that you check the JS libraries you are going to use are currently ready to use in TS. If the library already supports TS (and provides .d.ts file), no problem, but if not, please check a .d.ts file is provided by DefinitelyTyped.
For your specific use case, I'd look at using Angular so that you can lean on the Angular CLI which simplifies a lot of this. You'll have something building and on screen after a "git clone", "npm install", "npm start". Then check out including https://github.com/valor-software/ng2-charts to make integrating chart.js with Angular a breeze.
