In order to customize the core content of the HTML5Vi page source, these high level steps need to be taken:

Now that the plugin has been created with all the necessary files, a change needs to be made in the pageConfig.xml to instruct Strategy Web to use the custom HTML5VI_Content_Core instead of the original, on the HTML5Vi page used by Visual Insight Dashboards.
<framework>
<pages>
<page name="Html5Vi">
<templates>
<template>
<page-sections use-default="false">
<page-section file-name="@myPlugin:/jsp/HTML5VI_Content_Core.jsp" name="content_core" />
</page-sections>
</template>
</templates>
</page>
</pages>
</framework>
The following steps are optional, but may be useful in confirming that the above changes successfully pointed Strategy Web to the custom HTML5VI_Content_Core for the content section of the Visual Insight HTML5Vi page.

The jsp/asp resources used by Strategy Web are subject to change in newer versions, as the platform is further enhanced and defects are addressed. It is recommended to review the upgrading guidelines in the Web SDK Developer Zone before proceeding with an upgrade. In addition, it is also recommended to keep thorough documentation on any customizations made to jsp/asp resources, should they need to be repeated after a future upgrade.
If a plugin contains jsp/asp files and instructs Strategy Web to use the plugin version over the original, due to the pageConfig.xml within the plugin, upgraded environments may face unexpected behaviour until the modified jsp/asp files are updated to match those in the updated MSTRWeb/jsp or MSTRWeb/asp folders.
Any customizations to jsp/asp files in Strategy Web may need to be repeated after an upgrade, ensuring the latest version of the original jsp/asp file is copied from the updated MSTRWeb/jsp or MSTRWeb/asp folders.
Few scenarios require the modification of the jsp/asp page components used by Strategy Web as the only option. It is recommended to review alternative solutions to a customization scenario, if possible, as alternative methods (including CSS, javascript, and transform changes) may require less maintenance across future upgrades of Strategy Web.
