-- BUGS: X-Axis label format bug? (xAxisFormat =) https://en.wikipedia.org/wiki/Template_talk:Graph:Chart#X-Axis_label_format_bug?_(xAxisFormat_=)
-- Version History:
-- linewidths - doesnt work for two values (eg 0, 1) but work if added third value of both are zeros? Same for marksStroke - probably bug in Graph extension
-- 2016-01-09 _PLEASE UPDATE when modifying anything_
-- clamp - "clamp" used to avoid marks outside marks area, "clip" should be use instead but not working in Graph extension, see https://phabricator.wikimedia.org/T251709
-- 2016-01-28 For maps, always use wikiraw:// protocol. https:// will be disabled soon.
-- TODO:
-- 2016-03-20 Allow omitted data for charts, labels for line charts with string (ordinal) scale at point ___location
-- marks:
-- 2016-05-16 Added encodeTitleForPath() to help all path-based APIs graphs like pageviews
-- - line strokeDash + serialization,
-- - symStroke serialization
-- - symbolsNoFill serialization
-- - arbitrary SVG path symbol shape as symbolsShape argument
-- - annotations
-- - vertical / horizontal line at specific values [DONE] 2020-09-01
-- - rectangle shape for x,y data range
-- - graph type serialization (deep rebuild reqired)
-- - second axis (deep rebuild required - assignment of series to one of two axies)
 
-- Version History (_PLEASE UPDATE when modifying anything_):
-- 2020-09-01 Vertical and horizontal line annotations
-- 2020-08-08 New logic for "nice" for x axis (problem with scale when xType = "date") and grid
-- 2020-06-21 Serializes symbol size
-- transparent symbosls (from line colour) - buggy (incorrect opacity on overlap with line)
-- Linewidth serialized with "linewidths"
-- Variable symbol size and shape of symbols on line charts, default showSymbols = 2, default symbolsShape = circle, symbolsStroke = 0
-- p.chartDebuger(frame) for easy debug and JSON output
-- 2020-06-07 Allow lowercase variables for use with [[Template:Wikidata list]]
-- 2020-05-27 Map: allow specification which feature to display and changing the map center
-- 2020-04-08 Change default showValues.fontcolor from black to persistentGrey
-- 2020-04-06 Logarithmic scale outputs wrong axis labels when "nice"=true
-- 2020-03-11 Allow user-defined scale types, e.g. logarithmic scale
-- 2019-11-08 Apply color-inversion-friendliness to legend title, labels, and xGrid
-- 2019-01-24 Allow comma-separated lists to contain values with commas
-- 2018-10-13 Fix browser color-inversion issues via #54595d per [[mw:Template:Graph:PageViews]]
-- 2018-09-16 Allow disabling the legend for templates
-- 2018-09-10 Allow grid lines
-- 2018-08-26 Use user-defined order for stacked charts
-- 2018-02-11 Force usage of explicitely provided x minimum and/or maximum values, rotation of x labels
-- 2017-08-08 Added showSymbols param to show symbols on line charts
-- 2016-05-16 Added encodeTitleForPath() to help all path-based APIs graphs like pageviews
-- 2016-03-20 Allow omitted data for charts, labels for line charts with string (ordinal) scale at point ___location
-- 2016-01-28 For maps, always use wikiraw:// protocol. https:// will be disabled soon.
