According to embodiments of the present invention, one or more computer processors display unstructured data. One or more computer processors display a first chart that graphically represents at least a portion of the unstructured data. In response to the first chart failing to satisfy a user-defined criteria, one or more computer processors modifies the first chart to generate a second chart that graphically represents at least a portion of the unstructured data in a user-defined manner. In certain embodiments, the unstructured data includes information that does not have a pre-defined data model and/or is not organized in a pre-defined manner.
