Two of your ancestral lines can be followed back on their own: your fatherline (your father's father's father, and his) and your motherline (your mother's mother's mother, and hers). Your DNA test already named them. No coordinates and no DNA file needed — just the haplogroup.
What you get is a map of ancient burials: the excavated graves whose own DNA sits on your branch, each dated and placed where it was dug. It is not a map of where your branch is common today. For that, one tick shades the map by FamilyTreeDNA's testers and published present-day samples in each country, and the published samples come with it as a table.

One line is one ancestor per generation. Ten generations back you have about a thousand ancestors and this follows exactly one of them, so a haplogroup map is a thin slice of where you come from — a real slice, but a thin one.
The fatherline is read from the Y chromosome, which only men carry. The motherline is read from mitochondrial DNA, which everyone has.
That is why the price is per line, not per order: nobody should pay for a line they cannot be given.
Enter it as your test writes it — E-V32, R-M269, J-M267, or L3f1b, H1a1, U5b2a1. A terminal SNP such as E-V32 is safer than a long path like E1b1b1b2a1a2, because path names change between versions of the tree.
A haplogroup is one line out of thousands of ancestors. It is not proof of ethnicity or nationality, and the map shows where the line has been found, which is also a map of where archaeologists have dug.
The direct lines follow one ancestor per generation. A heatmap compares all of your DNA with present-day populations and ancient groups, and shows which burials are closest to you rather than merely sharing your branch.
