I was able to implement Luca's solution, but I had to make a few changes for it to work. My goal was to use D3.js with a Web Browser control for a Windows Forms Application (targeting .NET 2.0). It is working for me now. I hope this can help someone else.

 }
 finally
 {
 //Close the Registry
 if (Regkey != null) Regkey.Close();
 }
 }
 }
}
</code></pre>

Also, I added a string (ie_emulation) to the project's settings with the value of 11999. This value seems to be working for IE11(11.0.15).

Next, I had to change the permission for my application to allow access to the registry. This can be done by adding a new item to your project (using VS2012). Under the General Items, select Application Manifest File. Change the level from asInvoker to requireAdministrator (as shown below).

<pre><code>&lt;requestedExecutionLevel level="requireAdministrator" uiAccess="false" /&gt;
</code></pre>

If someone reading this is trying to use D3.js with a webbrowser control, you may have to modify the JSON data to be stored within a variable inside your HTML page because D3.json uses XmlHttpRequest (easier to use with a webserver). After those changes and the above, my windows forms are able to load local HTML files that call D3.

Combine the answers of RooiWillie and MohD 
and remember to run your app with administrative right.

<pre><code>var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";

 else if (BrowserVer == 10)

 else if (BrowserVer == 9)
 RegVal = 9999;

blocks|key|1693724|text|我不需要更改RegKey，而是可以在我的HTML头中放一行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1693725|<html>

Rather than changing the RegKey, I was able to put a line in the header of my HTML:

<pre><code>&lt;html&gt;
 &lt;head&gt;
 &lt;!-- Use lastest version of Internet Explorer --&gt;
 &lt;meta http-equiv="X-UA-Compatible" content="IE=edge" /&gt;

 &lt;!-- Insert other header tags here --&gt;
 &lt;/head&gt;

blocks|key|1694043|text|它的一个便宜和简单的解决方法是，您可以只在FEATURE_BROWSER_EMULATION键中放入一个大于11001的值。然后使用系统中可用的最新IE。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1694044|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

A cheap and easy workaround for it is that you can just put a value which is bigger than 11001 in the FEATURE_BROWSER_EMULATION key. Then it takes the latest IE that is available in the system.

blocks|key|1907622|text|只需将以下代码添加到您的html中即可完成无需注册表settigns的操作|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1907623|<meta+http-equiv="X-UA-Compatible"+content="IE=11"+>|code-block|syntax|javascript|1907624|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

just adding the following to your html does the trick no need for registry settigns

<pre><code>&lt;meta http-equiv="X-UA-Compatible" content="IE=11" &gt;
</code></pre>

blocks|key|1907668|text|最好是强制使用尽可能高的模式。这可以通过添加以下内容来实现：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1907669|<meta+http-equiv="X-UA-Compatible"+content="IE=edge">|code-block|syntax|javascript|1907670|为了支持IE，最好包含polyfill库：|1907671|<script+src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>|1907672|在任何脚本之前。|1907673|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

It is best to force the highest mode possible. That can be accomplished by adding:

<pre><code>&lt;meta http-equiv="X-UA-Compatible" content="IE=edge"&gt;
</code></pre>

and it is always good to include the polyfill library in order to support IE:

<pre><code>&lt;script src="https://polyfill.io/v3/polyfill.min.js?features=es6"&gt;&lt;/script&gt;
</code></pre>

before any script.

The default version of the webbrowser control in a C# <a href="http://en.wikipedia.org/wiki/Windows_Forms">Windows Forms</a>
