Figure Extraction

Welcome to the release of our Figure Extraction feature! This functionality allows users to extract data from charts and figures in PDF documents.

Key Highlights

Extract raw data from figures effortlessly.
In our first release, we focus specifically on data extraction from bar charts. Vertical, horizontal, grouped, and stacked bar charts are all supported.
We recommending using the document_type=hierarchical_v2 when using Figure Extraction. This gives the best performance in our testing.

Getting started

To apply Figure Extraction to your document, add "figure_extraction": "true" to the data dictionary in requests.post:

Python

response = requests.post(
    api_url,
    files=files,
    data={
        "document_type": "hierarchical_v2",
        "figure_extraction": "true"
    }
)

Important Notes

Please expect throughput and latency increases when using Figure Extraction.
Today we support bar charts. Support for additional chart types such as line plots, scatter plots, and pie charts is coming soon.
Accuracy is best for charts with the text of the chart embedded into the document (we call these "native" charts).
Feedback is encouraged to improve accuracy and expand the types of charts we support.
