# Simulation

Simulation allows users to add, delete, and edit nodes within a chart. This functionality is available even in read view.

{% hint style="warning" %}
Please note that:

* Since the visual is Microsoft Certified, there is no writeback capability applicable. 
* The simulations done in read view will be available only for that particular session and will be lost upon reload. The simulations done in edit view of the report will be saved in the visual tile; if the tile is deleted, the simulation will be deleted. 
* However, the simulated data can be exported as shown in [#simulation-section-in-the-toolbar](#simulation-section-in-the-toolbar "mention")
  {% endhint %}
