thank you . that was really helpful ,

Hi. If you mean talking about charts, there is a section on this site "reporting changes" which might help you with that. It helps you with the vocabulary to describe charts and graphs. There are other activities on that page which are also helpful as the whole page deals with business English. http://bogglesworldesl.com/businessESL.htm Go to Reporting Changes.

Do you mean presentations? A chart is a diagram (picture) that is used to explain. There are many types of charts to represent many types of information.
