Read the values off the attached {{chart-type}} and return them as a table with one row per {{series-or-category}}.
You have a crop tool and an image container with PIL and OpenCV. Use them: crop to each axis to read the scale, crop to the legend, then crop to each data region at higher magnification before you state a number. Measure pixel positions against the axis scale rather than estimating by eye. Verify any value that sits near a gridline by cropping again.
Report each value with the crop you read it from and a confidence of high, medium, or low. Where two series overlap and cannot be separated, say so rather than guessing. If the image resolution is too low to resolve {{smallest-unit}}, stop and ask for a higher-resolution export before continuing.Dense Chart Reading With a Crop Tool
Generate a detailed reading of values from a chart image using image processing techniques to provide accurate data visualization analysis in a table format.
