// Add this tag to your template to include a chart
// Orders Prices by months<<y [Sum(c => c.Price)]>><<size [Count()]>>

// Provide the file path to your template
// PDF templates are not supported at this time.
String template = "chart_template.docx";

// Extract the necessary data from your source
DataSourceInfo data 
    = new DataSourceInfo(GetChartData(), "orders");

// Save the final document with the embedded chart
DocumentAssembler asm = new DocumentAssembler();
asm.assembleDocument(template, "result.pdf", data);
