Abstract: We present a controlled user study evaluating the effectiveness of bundled curve representations in parallel coordinates plots. Replacing the traditional C0 polygonal lines by C1 continuous piecewise Bézier curves makes it easier to visually trace data points through each coordinate axis. The resulting B´ezier curves can then be bundled to visualize data with given cluster structures. Our results show that: 1) compared to polygonal lines, bundled curves are equally capable of revealing correlations between neighboring data attributes; 2) the geometric cues of bundles can be effective in displaying cluster information.
