A system includes reception of a request to display a data chart. In response to the request, a cached version of the data chart is retrieved from a memory, the cached version of the data chart is displayed, and while the cached version of the data chart is displayed, current data of the data chart is requested from a remote data source. Also while the cached version of the data chart is displayed, an active version of the data chart is rendered based on the current data. The displayed cached version is then replaced with a display of the rendered active version.
