Direct Manipulation Graphics for Data Mining

Data mining has attracted a lot of attention in recent years, but there has been proportionately little attention paid to the contribution data visualisation could make. Checking data quality, monitoring analyses, interpreting and comparing results are all areas in which modern graphics tools have a role to play. Some existing graphical displays can be scaled up successfully, some new displays will be needed, but all should be directly interactive. This paper outlines the key ideas of direct manipulation graphics for data visualisation and describes the contribution they can make to all stages of the data mining process.
