A small Belle II data sample will be available to the general public through an interactive graphical application which includes basic particle selection tools for reconstructed particles. The application is using an open source library Blockly running in an HTML5 capable browser. In the application, different particle decays can be described by selecting and combining particles from the data file. The application includes easy histogramming and cutting tools and enables display of the ROOT histograms. After submission, a pseudocode is generated by the user interface. The code is interpreted by the server which then runs back-end analysis and sends back the resolution histograms to the client. The browser app also enables for the interactive fitting of the histograms, thus enabling even more complex analyses. The application can be run on a single public web server aimed at a single access or in a virtual appliance for use in a classroom consisting. The virtual appliance consists of a Linux OS, data sample, an analysis framework and a private web server. In the presentation, I will describe the application, demonstrate its use and outline our plans for future development.
