Dynamic queries are gaining popularity as a method for interactive information visualisation. Many implementations have been made on personal computers, and there is increasing interest in Web-based designs. While Java and Flash strategies have been developed, we believe that a Dynamic HTML implementation could help promote more widespread use. We implemented double-box range sliders with choropleth maps and scattergrams, which are two popular visualisations, using HTML layers and tables. This paper describes our methods for slider control, visual presentation, and displaying/updating results for these visualisations. Visual design issues innovations and performance enhancements were necessary to create viable designs.
