### What is this PR for?

Can't display the same chart again. I attached a screenshot.

- this is the same fix with #2110
- except refactoring PR
- based on branch-0.7

and

- CI failure might be related with #2103

#### Implementation Details

After #2092,

- result.html will draw chart every time since we use `ng-if` instead of `ng-show`
- that means DOM is deleted, and created too
- so we have to create visualization instance every time which requires a newly created DOM.

```js
builtInViz.instance = new Visualization(loadedElem, config); // `loadedElem` is the newly created DOM.
```
