Diagram is totally different from other writing task 1. You will find more or less similarity among the 4 writing task 1 except diagram. For diagram you need to know some certain rules. It is similar to process writing. If you can remember process writing, you will find that the process follows some steps. You have to describe the things step by step. The important thing is you have to understand from where the process begin and how many steps are there. Sometimes you can divide that mainly into two parts.
You have to write a general statement and a thesis statement at the beginning as an introduction. Then you will use some linkers to write the process properly. In this case you should use some linkers like firstly, secondly, thirdly, afterwards, next, etc.

Firstly, the natural process has both the condensation and evaporation process. In the natural process the water is shined by the sun and the water is evaporated into the cloud and the cloud falls down into the reservoir during the time of rain.
Secondly, the rain water flows from the reservoir to the turbine through pipe where a valve control the volume of water. Afterwards, the water is pushed back to the reservoir by a pump. This is the first step of the mechanical process.
Finally, the turbine converts water into electricity. In this part the step two of mechanical process begins where turbine plays a central role to produce electricity. From the spinning of the turbine, the electricity is produced and that is sent to the transformer station through a high voltage cable. After that the electricity becomes ready for the use. By an underground cable the electricity is sent to the schools, hospitals, factories, household and to the customers.
