Bar Chart (PNG)
A clean bar chart of monthly revenue with axis labels, gridlines, and value labels — a real-world fixture for testing chart-extraction and OCR tools, vision models, and thumbnail rendering.
Chart images for recognition and extraction
Bar, line, pie, and scatter charts rendered as images with labelled axes, legends, and known values — for testing chart-extraction and chart-to-data tools, vision models, and OCR of embedded text.
Line Chart (PNG)
A two-series line chart (desktop vs. mobile visitors) with markers, a legend, and gridlines — for testing chart parsing, trend extraction, and image pipelines against a known plot.
Pie Chart (PNG)
A five-slice pie chart of traffic sources with percentage labels and a legend — a real-world fixture for chart-recognition, segmentation, and OCR of embedded text.
Scatter Plot (PNG)
A scatter plot of 120 seeded points (order value versus items per order) showing a positive correlation, with labelled axes — for testing point-cloud extraction and chart parsing.
Bar Chart (SVG)
A bar chart drawn as vector SVG — axis, gridlines, labelled bars — the scalable counterpart to the raster chart images, for testing SVG chart rendering and vector conversion.
