Many information visualization techniques rely on interaction as a key element in their functionality and use. However, information visualizations and infographics when produced in printed form become non-interactive static visuals. To enable printed information visualizations and infographics to offer a type of interaction, QR codes can be introduced producing data drill down interactivity. QR codes are small 2D matrices that can hold compressed information. The addition of QR codes allows for additional information be extracted from the visualizations. This additional information can then be easily captured and recorded. QR codes, due to their small size, high bandwidth, and error correction capabilities lend themselves to inclusion in information visualizations and offer the possibility of information drill down interaction in printed visualizations.
