How visualize data that are published via MQTT as a website?

A IoT device publish its data via tcp/ip sockets and MQTT. Now I like to process these data inside the web browser and create a beautiful interactive GUI. Since I have no idea in web page programming, I am asking for typical ways to approach that topic. The web page I am looking for should open the MQTT connection, receives the data and visualize it. That should happens inside the web browser so it uses the Laptops/PCs/Phones CPU to do the data processing. This is needed because the MQTT IoT device does not have much computation power. Any ideas, toolchains, frameworks to approach that problem?
