You cannot create or display a Gantt chart with standard features of kintone.
However, it is possible to display a Gantt chart using customization or plug-ins.

Cybozu developer network, the website for developers, provides a plug-in for Gantt charts. By applying this plug-in, you can display a Gantt chart in kintone. To use a plug-in, you first need to import the plug-in zip file in kintone Administration and then add the plug-in in an app's App Settings.
For details on the Gantt chart plug-in and how to apply it, refer to the following pages.
