The origin
A cluster in a line graph is the major part of the line graph that connects to the plot.
Then that part of the graph is below the x-axis.
A pie graph
the part affected cross eye is eyes
A key can make it easier to interpret the data sets that each part of the graph represents, especially if there is no room in the graph area for labels.
There is nothing in the definition of "asymptote" that forbids a graph to cross its asymptote. The only requirement for a line to be an asymptote is that if one of the coordinates gets larger and larger, the graph gets closer and closer to the asymptote. The "closer and closer" part is defined via limits.

the x-axies
A cluster in a line graph is the major part of the line graph that connects to the plot.
If they things you are comparing part of a whole, pie graph. If not, bar graph.
It is the legend or key.
It is somewhat subjective what the most important part of a graph is. It is very important that you label each axis.
A pie graph
Then that part of the graph is below the x-axis.
A circle graph
Each segment of the circle graph represent a part of the whole.
The graph could go on forever while a data table only shows a part of the graph.
