HTML code support?

Does CHB support HTML coding? I notice in the rich editor there is the option to insert three types of code (Gernal, PHP and HTML) but I tried to insert a couple of bits of code which I'm pretty sure are correctly written and when I checked the post preview they didn't appear as anything other than the code text. Is HTML code actually supported?

For example, I'd like to embed the following Google Trend analysis (mobile): but this is what it looks like when I use the HTML code editor:

<script type="text/javascript" src=""></script> <script type="text/javascript"> trends.embed.renderExploreWidget("GEO_MAP", {"comparisonItem":[{"keyword":"Deontay Wilder","geo":"US","time":"today 1-m"},{"keyword":"Anthony Joshua","geo":"US","time":"today 1-m"}],"category":0,"property":""}, {"exploreQuery":"date=today%201-m&geo=US&q=Deontay%20Wilder,Anthony%20Joshua","guestPath":""}); </script>
EDIT: On second thoughts, is that because it's javascript? The embed option on Google Trends says "Paste this into any HTML page". I guess the forum doesn't support java is that right?
