Abstract: A visualization displays a portion of a big data set in a control in a browser-based GUI. The browser may support HTML and the control may include a DOM element. The control includes a canvas for rendering the big data portion. To create the visualization, the smaller of the browser's maximum canvas size and the big data set's candidate canvas size is determined. The canvas is sized accordingly. A page in the canvas is filled with initial data and the visualization is displayed with a scrollbar. Upon receiving a user input, it is determined if the user input denotes a short or long scroll. It is also determined if the scroll reaches an end of the scrollbar. Data is fetched from a relative location in the big data set in proportion with the relative scroll position, and respecting the data set and canvas limits.
