The mapping tool is currently located at:
More about it and pictures in my August 3 blog post.
Use my other tool, the segment mapper, to make a chart of overlapping segments from relatives or possibles for up to 40 possible relatives. And use my one chromosome mapper for a detailed look at overlaps on a single chromosome.
The Chromosome Mapper requires the column headings and contents as listed below, case sensitive, in any order, in your CSV spreadsheet. It is intended as a tool for picturing your ancestral DNA as determined from known relatives as opposed to showing your DNA overlaps from unknown relatives.
Mac users getting errors please read the article on creating a CSV for some solutions.
To better understand the chromosome mapping concept, read the ISOGG wiki article on mapping. Also I have an article on making a spreadsheet of your chromosome matches on this blog.
Once you have a spreadsheet that you want to make a picture from, that sheet has to be saved as a CSV (comma separated values) text file in order for this tool to make a chromosome map from it.
Rebekah Canada has done a really nice step by step tutorial of how to use this tool with screen shots on her blog here:

Current List of Required Columns in your CSV file for this Tool
|Column name||Alternate Name||Must Contain this Data|
|side||This column is optional, selectw which side (warm or cool colors) the segment appears on.To use it put the letter M or P or any words starting with those letters to indicate maternal or paternal side of your tree, this must be added by you to any CSV downloaded from 23andme or Family Tree DNA or DNAgedcom|
|MRCA||Comparisonor any column name you specify||Most Recent Common Ancestor(s) – this is the name to use in the chromosome map picture, you can tell the program to use a different column name for this.|
|chr||Chromosome||Chromosome number 1-22 or X|
|Start||Start point||The starting number for the segment location used by 23andme and Family Tree DNA, in the 23andme ancestry these numbers are divided by 100,000 so check the box for decimal if you are using that style of number.|
|End||End point||The ending number for the segment (see above comment).|
|cMs||centiMorgans (cMs)||The number of centimorgans in the segment, used for display purposes only. Since this is for display only you can put anything in this column for example I put the relative then a dash and the cMs|

Programming is how I make my living so a small donation of $5 or $10 would be most appreciated, if you find this tool useful.
