Create website and display live plot

I have aws lambda setup to receive array or 768 number temperature in celcius. Eg [23.33, 24.22, 24.98, 25.87, 25.01........768] and stored in aws dynamodb. It updates every 5 second. New Temperature is generated every 5 second from raspberry pi from sensor in raspberry pi of (24*32).

I want to build a website that can show the interactive plot or heatmap by using the temperature data from dynamodb or another aws service.
Also website need username and password to ciew its data
