This webpage provides a list of useful tools for visualising data sets for those with and without coding skills. Most of the tools listed have basic, free accounts however the fact that usability is often greatly increased by monthly subscription fees is a drawback. However, the list does provide a good overview of what is available and it's likely that if you're looking for a simple way to represent your data, you'll find something useful - either by using the tools to create a visualisation, or simply looking through the examples to find inspiration to go off and create your own.
