Chart-to-Text Dataset

Each dataset folder (Statiata or Pew) has the following structure:

├── dataset folder                  
│   ├── bboxes # Json files that contain the list of words and their bounidng boxes that were detected in the Chart Images.   
│   │   │   ...
│   │   │   ...
│   └── captions # Text files that contain the target summaries/captions for the chart images.
│   │   │   ...
│   │   │   ...
│   └── data # CSV or Txt files that contain the underlying data table for each chart image.   
│   │   │   ...
│   │   │   ...
│   └── imgs # Chart images (png format)  
│   │   │   ...
│   │   │   ...
│   └── titles # Txt files the contain the titles of the chart images.  
│   │   │   ...
│   │   │   ...
│   └── dataset_splits # CSV files that contain a list of the chart images names for each split (train/val/test)
│   │   │   ...
│   │   │   ...
│   └── **multiColumn** # A folder with the same structure, but it contains the multicolumn charts (e.g., stack bar charts, multi line charts). 
│   │   │   ...
│   │   │   ...
│   └── metadata.csv # A csv file that contain extra metadata that were saved during the crawling process (title, x-axis label, y-axis label, ..etc).
│   └── sta.txt # A text file with some statistics about the data in the folder.
