Images as labels

Is there any way to use images as labels? I need to be able to do something like this:

`radar_chart.x_labels.append (my_icon.jpg)`

Thanks
Jose

Start by locating the x_labels handling in pygal and determine how labels are represented and rendered. Define the supported image input and expected chart output before implementing the feature, then add coverage showing that an image can be used as an axis label.
