CKAN’s data previewing tool has a host of powerful features for previewing data stored in the DataStore.
Graphing data: You can also display the data on a graph, choosing the variables on the axes and comparing a number of variables by graphing them together on the same y-axis.
Image data: CKAN’s previewing is not restricted to tabular data. Common image formats will be displayed, and if a resource is a web page, it will also be previewed directly in the CKAN dataset.
Roll your own: CKAN’s built-in previews use the DataStore’s API. If you have your own data previewing tools or are planning to build them, it’s easy to plug them into the API so that you can create visualisations on the fly, without the need for users to download the data.
