You DO know no pictures attached :D
This is the only one I can share:
The bar chart depicts the percentage of men and women who enrolled in five different post-school qualifications in Australia in the year 1999.Overall,it can be seen that the highest percentage of females studied Under graduate diploma.Whereas,most of the males were interested in Skilled vocational diploma compared to other qualifications.
Some IELTS practice books commonly keep this area, which is the intro and overview written as one para. However, if you think you need to earn a good score for coherence and cohesion by using paragraphing sufficiently and appropriately, then you don't need to write the intro and overview in the same paragraph.
To conclude,
You don't need to include a conclusion for this part. Perfectly summarize this report including: an intro,an overview, two bodies (similarities and/or diversities)
