'the development of the disease tuberculosis in England' my graph description

hi everyone..
I am from Germany and i will write a test about describing graphs..
here I have an example, the content is not correct but the wording and the grammar should be properly.

"The graph above shows the development of the disease tuberculosis in England over a 10-year period.
As you can see from the diagram there were at least 100.000 people in 1983 who were afflicted with tuberculosis.
In 1984 that number remained constant. Between 1984 and 1987 there is a slight rise to see, which however fells down in 1988 to 100.000 again.
What I am about to show you now should be of considerable interest, because after 1988 the figure of the people with tuberculosis boomed until 400.000 in 1989 and the graph reaches its peak.

But starting in 1990 the illness regressed and reached the lowest point in 1992, namely 0.
Thats because it has been found an antidote against the disease."

You seem to understand how to describe the graph.
You might historically talk about events/reasons leading up to milestones (peaks or valleys) on the graph.
Such as "between 1984 and 1987" there was a news story about a rise in childhood T.B., and perhaps that contributed to the increase we see

or
"after 1988 the figure of the people with tuberculosis boomed until 400.000 in 1989" which was due to a rise in immigration. There was a news story of 5 immigrants that died at so-and-so hospital in City, Germany along with a boarding house that was closed by authorities due to conditions of disease/overcrowding. Two of the people from the house were found to have T.B.
