<ul>
- <li><strong>Score:</strong> 1.00 is the value of one pawn (in a balanced endgame). Positive values are better for white.</li>
+ <li><strong>Score:</strong> 1.00 is roughly one pawn
+ (<a href="https://github.com/official-stockfish/Stockfish/commit/ad2aa8c06f438de8b8bb7b7c8726430e3f2a5685">technically</a>,
+ 50% win probability for a computer). Positive values are better for white.</li>
<li><strong>PV:</strong> Principal Variation, the series of moves the engine thinks is the best.</li>
<li><strong>Thick red line:</strong> Marks the best move (in the view of the engine). Multiple chained arrows
means that the PV starts with multiple successive moves with the same piece, ie., the engine thinks
is forced or nearly so.</li>

- * Attribute not equal selector
- * Positional selectors (:first; :eq(n); :odd; etc.)
- * Type selectors (:input; :checkbox; :button; etc.)

- * Reliable functionality on XML fragments
- * Requiring all parts of a selector to match elements under context
- * (e.g., $div.find("div > *") now matches children of $div)
- * Matching against non-elements
- * Reliable sorting of disconnected nodes
- * querySelectorAll bug fixes (e.g., unreliable :focus on WebKit)

- 3. Use the same single mechanism to support "private" and "user" data.
- 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
- 5. Avoid exposing implementation details on user objects (eg. expando properties)

-* Usage:
-* $(selector).sparkline(values, options)
-*
-* If values is undefined or set to 'html' then the data values are read from the specified tag:
-* <p>Sparkline: <span class="sparkline">1,4,6,6,8,5,3,5</span></p>
-* $('.sparkline').sparkline();
-* There must be no spaces in the enclosed data set
-*
-* Otherwise values must be an array of numbers or null values
-* <p>Sparkline: <span id="sparkline1">This text replaced if the browser is compatible</span></p>
-* $('#sparkline1').sparkline([1,4,6,6,8,5,3,5])
-* $('#sparkline2').sparkline([1,4,6,null,null,5,3,5])
-*
-* Values can also be specified in an HTML comment, or as a values attribute:
-* <p>Sparkline: <span class="sparkline"><!--1,4,6,6,8,5,3,5 --></span></p>
-* <p>Sparkline: <span class="sparkline" values="1,4,6,6,8,5,3,5"></span></p>
-* $('.sparkline').sparkline();
-*
-* By default, options should be passed in as teh second argument to the sparkline function:
-* $('.sparkline').sparkline([1,2,3,4], {type: 'bar'})
-*
-* Supported options:
-* lineColor - Color of the line used for the chart
-* fillColor - Color used to fill in the chart - Set to '' or false for a transparent chart
-* width - Width of the chart - Defaults to 3 times the number of values in pixels
-* height - Height of the chart - Defaults to the height of the containing element
-* chartRangeMin - Specify the minimum value to use for the Y range of the chart - Defaults to the minimum value supplied
-* chartRangeMax - Specify the maximum value to use for the Y range of the chart - Defaults to the maximum value supplied
-* chartRangeClip - Clip out of range values to the max/min specified by chartRangeMin and chartRangeMax
-* chartRangeMinX - Specify the minimum value to use for the X range of the chart - Defaults to the minimum value supplied
-* chartRangeMaxX - Specify the maximum value to use for the X range of the chart - Defaults to the maximum value supplied
-* tagValuesAttribute - Name of tag attribute to check for data values - Defaults to 'values'
-* disableInteraction - If set to true then all mouseover/click interaction behaviour will be disabled,
-* making the plugin perform much like it did in 1.x
-* disableTooltips - If set to true then tooltips will be disabled - Defaults to false (tooltips enabled)
-* disableHighlight - If set to true then highlighting of selected chart elements on mouseover will be disabled
-* defaults to false (highlights enabled)
-* highlightLighten - Factor to lighten/darken highlighted chart values by - Defaults to 1.4 for a 40% increase
-* tooltipContainer - Specify which DOM element the tooltip should be rendered into - defaults to document.body
-* tooltipClassname - Optional CSS classname to apply to tooltips - If not specified then a default style will be applied
-* tooltipOffsetX - How many pixels away from the mouse pointer to render the tooltip on the X axis
-* tooltipOffsetY - How many pixels away from the mouse pointer to render the tooltip on the r axis
-* tooltipFormatter - Optional callback that allows you to override the HTML displayed in the tooltip
-* callback is given arguments of (sparkline, options, fields)
-* tooltipChartTitle - If specified then the tooltip uses the string specified by this setting as a title
-* tooltipPrefix - A string to prepend to each field displayed in a tooltip
-* tooltipSuffix - A string to append to each field displayed in a tooltip
-* tooltipSkipNull - If true then null values will not have a tooltip displayed (defaults to true)
-* tooltipValueLookups - An object or range map to map field values to tooltip strings
-* (eg. to map -1 to "Lost", 0 to "Draw", and 1 to "Win")
-* numberFormatter - Optional callback for formatting numbers in tooltips
-* numberDigitGroupSep - Character to use for group separator in numbers "1,234" - Defaults to ","
-* numberDecimalMark - Character to use for the decimal point when formatting numbers - Defaults to "."
-* numberDigitGroupCount - Number of digits between group separator - Defaults to 3
-*
-* There is 1 type of sparkline, selected by supplying a "type" option of 'bar' (default),
-*
-* bar - Bar chart. Options:
-* barColor - Color of bars for postive values
-* negBarColor - Color of bars for negative values
-* zeroColor - Color of bars with zero values
-* nullColor - Color of bars with null values - Defaults to omitting the bar entirely
-* barWidth - Width of bars in pixels
-* barSpacing - Gap between bars in pixels
-* zeroAxis - Centers the y-axis around zero if true
-*
-*
-*
-*
-*
-*
-* Examples:
-* $('#sparkline1').sparkline(myvalues, { lineColor: '#f00', fillColor: false });
-* $('.barsparks').sparkline('html', { type:'bar', height:'40px', barWidth:5 });
