Create VDX Diagram in Java

// Get your ClientId and ClientSecret from https://dashboard.aspose.cloud (free registration required).
DiagramApi api = new DiagramApi("client_credentials", "MY_CLIENT_ID", "MY_CLIENT_SECRET");

String fileName = "sample.vdx";
String folder = "my_output";
Boolean is_overwrite = "true";
CreateNewResponse response = api.postDiagramConvert(fileName, folder, is_overwrite);
