in lib/types/chart-type.ts, ChartType.WordTree should be 'WordTree' not 'wordtree'

Bug Report

Description

lib/types/chart-type.ts defines enum ChartType. The last enum value is WordTree = 'wordtree' but should be WordTree = 'WordTree'.

To reproduce

1. Visit this StackBlitz
2. Open app.component.ts, which declares data used in sample charts.
3. wType=ChartType.WordTree; produces an error: Invalid visualization type: wordtree
4. wType = "WordTree" as ChartType; is a wordaround that shows the wordtree.

FYI - I found this while trying to debug another problem. WordTree worked fine for me (in Jan 2021), and then at some later point (not sure when) it stopped working. I don't think I changed anything (but it's certainly possible). Now I get a "TypeError : c is undefined" after ScriptLoaderService.loadChartPackages() calls https://www.gstatic.com/charts/loader.js.

I'm not sure if these problems are related, but the ChartType.WordTree problem might cause problems for getPackageForChart(), which could cause other problems.

I updated the StackBlitz to angular-google-charts 2.2.2, and now it also gives the error "c is undefined".
Should I open this as a separate issue?

Hi,
Any update on the issue ? Anyone working on this? After I tried the workaround provided by @kussmaul it gives me the below error.

@FERNman Please if you could look into the issue?

I was able to get around the toLowerCase issue by reverting to 1.1.6, and using the "WordTree" as ChartType as previously mentioned by kussmaul. Hope this helps someone that is able to still use 1.1.6.

FYI - in 2.1.0, 'WordTree' as ChartType works. However, in 2.1.1, I get c is undefined.
Looking at the difference, I suspect the problem is that chart.helper.ts:ChartTypesToPackages uses the (wrong) ChartType.WordTree.

However, fixing chart-type.ts (as in PR #277), now chart-type.d.ts, does fix the problem (in 2.2.3).
