+# SciChart.js Chart Initialization and Cleanup Test
+
+The purpose of this app is to serve as a testing boilerplate for charts to check for memory consumption and potential leaks.  
+It allows to create surfaces of different types (2D and 3D) with different `wasmContext` ownership options:
+
+- Single - a surface with a separate `wasmContext` ( initialized via `createSingle`)
+- Multi - a surface with a shared `wasmContext` ( initialized via `createSingle`)
+
+Also it allows to delete surfaces one by one or simultaneously.
+There are also an option to delete shared `wasmContext` (both 2D and 3D) and test `autoDisposeWasmContext` options.
+
+The app demonstrates a usage of internal memory and performance debug utils.  
+The Memory Debug utils require the app to be run in development mode.
+
+Before running the example get familiarized with related documentation:

+[Memory Best Practices](https://www.scichart.com/documentation/js/current/webframe.html#MemoryBestPractices.html)

+
+## Running the project
+
+Setup:
+`npm install`
+
+Run in development mode:
+`npm run dev`
+Run in production mode:
+`npm run build`
+`npm start`
+
+## How to use
+
+We recommend testing this example both in a regular manner and by trying to force the garbage collection.
+Also, perform testing on a freshly opened tab with incognito mode.
+
+Prepare the browser dev tools to be able to force a garbage collection and taking a heap snapshot.
+
+### Data Series update without initial capacity
+
+Force garbage collection and make a heap snapshot with dev tools.
+Press some "Create Chart" buttons to initialize surfaces.
+Then use appropriate "Delete" buttons.
+During the process consider making snapshots, logging debug output.
+
+Experiment with different params
