There are a few ways to make graphs in Google Sheets. The first way is to use the built-in graph function. To do this, select the cells you want to graph and go to Insert > Chart. From there, you can select the type of chart you want to create.

Another way to make a graph is to use the Google Sheets add-on, called Create Graphs. To use this add-on, you first need to install it. To do this, go to the Add-ons menu and select Get Add-ons. Then, in the search bar, type "Create Graphs" and select the add-on from the results.

Once the add-on is installed, you can open it by going to Tools > Create Graphs. This will open a new sheet with a graph already created. To customize the graph, you can select the cells you want to include and then change the settings in the sidebar.
