Isomatic is a website for making professional pictograms from the users own data. The site has numerous examples of how the tool can be used, which is good for deciding which style you would like to use. There are a variety of features to choose from which are found to the left of the map making it easy to customise (see image below).
It is also possible to export the map using the menu at the top of the page. The graphs that can be produced using this site are very simple, therefore there are limits on the complexity of the information that can be used. Below is an example of the type of dataset that can be used.
Overall I would rate this site as a 3/5, as it gives people the ability to create aesthetically pleasing maps but limits the amount of data that can be represented.
