VLDB Journal paper on visualization-driven data aggregation

Dear readers,
I like to inform you that the main paper about my research of the past 2-3 years has been published [1] in the The VLDB Journal. It is based on my award-winning paper about the M4 aggregation [2] for line charts. It generalizes and extends the M4 approach to the most common chart types, such as bar charts, scatter plots, space-filling visualizations, and also describes how to conduct visualization-driven data aggregation in chart matrices.

For more details, I suggest to have a look at the papers [1, 2].
