Analogue of UiApp.createApplication()?

Question

I need help, try to use HtmlService.createHtmlOutput() but it doesn't work... Sorry, only begin to learn

function doGet() {
           var data = Charts.newDataTable()
               .addColumn(Charts.ColumnType.STRING, "Month")
               .addColumn(Charts.ColumnType.NUMBER, "In Store")
               .addColumn(Charts.ColumnType.NUMBER, "Online")
               .addRow(["January", 10, 1])
               .addRow(["February", 12, 1])
               .addRow(["March", 20, 2])
               .addRow(["April", 25, 3])
               .addRow(["May", 30, 4])
               .build();

           var chart = Charts.newAreaChart()
               .setDataTable(data)
               .setStacked()
               .setRange(0, 40)
               .setTitle("Sales per Month")
               .build();

           /*var uiApp = UiApp.createApplication().setTitle("My Chart");
           uiApp.add(chart);*/

           var uiApp = HtmlService.createHtmlOutput();
           uiApp.setContent(chart);

           return uiApp;
         }

It looks like you copied this code from the Google Charts overview page. There are a lot of ways to use the chart function however.

If you're just trying to learn about it I recommend starting with learning the HTML associated with the charts service. Here is the developers Quick Start Guide which should walk you through how to create the appropriate html content. You can then use the HTMLService to display the content.
