Web page generation from Perl/Python script or similar

General information for the business: Well sell WAN and Internet connectivity products
Description of requirements/functionality: We generate graphs for certain products with usage statistics. These are all the same fixed width/height. At present these are dumped to local files on the linux server for each customer/application.

We need a perl/python or similar script that will generate a HTML page with our logo, some text and the images mentioned above and ideally have it PDF that page and email it. There will be hundreds of customers going forward so any way to remove method of building each variable (i.e customer email and exact .png files to show) would be good (perhaps a webpage or shell script that creates a script from the variables).
Specific technologies required: HTML, PERL, PYTHON, PDF
OS requirements: Linux
Extra notes: The Linux server is running CentOS 6.9
