Sample Data

Below you can find samples from each training set. We provide a few chart images with their corresponding annotations in a JSON file. The inputs and expected outputs for each sub-task are specified in the JSON file. Key values that begin with an underscore (_) are not required output, but are given as part of the ground truth annotations, in case this information is useful.
