This web page and corresponding images have been generated using Python_Evolution_ID_018.py script. Script takes as an input this timeline_data_file_11.txt datafile. Script generates a poster-size image of timeline in logarithmic scale as well as this web page.

Example of script usage:

$python Python_Evolution_ID_018.py TimeLine timeline_data_file_11.txt 2006 2005 pilfonts

where:
TimeLine - prefix for output files
timeline_data_file_11.txt - input datafile
2006 - end of timeline
2005 - current year
pilfonts - directory with PIL fonts

Upon execution script generates four output files:
TimeLine.large.png - large timeline image
TimeLine.small.png - small timeline image
TimeLine.part.png - cropped part of large timeline image
TimeLine.html - this web page

Input file format timeline_data_file_11.txt:
1-st column - time [three formats: YA or BC or AD]
2-nd column - time metric [YA - years ago; BC - Before Christ (Before Common Era); AD - Anno Domini (Common Era)]
3 -d column - event [description of an event/datapoint]
4-th column - event scale [great; large; small]
5-th column - event type [time; geo; life; plant; info; tech; web; hist]
6-th column - display/hide ["+" - to display; "-" - to hide (skip)]
7-th column - google keywords [Keywords for Google Web search]

5 PIL fonts were used in this script:
helvB24.pil helvR24.pil helvR18.pil helvR14.pil helvR12.pil
helvB24.pbm helvR24.pbm helvR18.pbm helvR14.pbm helvR12.pbm

It is hard to express/display all credits for data obtained via Web search. Instead of the full list of credits a column "Google search" of this table displays keywords which were used to collect data.
