  • Publication number: 20230237076
    Abstract: A computer-implemented method, system and computer program product for automatically drawing infographics. Variables of a dataset are received from a computing device that were selected by the user of the computing device. For those selected variables that are associated with a data model, a procedure to draw infographics for variables assigned or not assigned the role of a target using the data model associated with each of the variables assigned or not assigned the role of target, respectively, is implemented. Alternatively, if the selected variables are not associated with a data model, then such variables are assigned a level of measurement as well as assigned the role of input. Such assignments become the data model which, along with the metadata (e.g., values of the variable) obtained by parsing the original data, are used to implement the procedure to draw infographics for variables not assigned the role of a target.
