Center the charts and the chart heading text
Mobile: Can't figure out how to modify SVG

For the mobile to work, the svg charts has to shrink but the svg
amCharts generated has its set width and hight.

n.php, but we still need to modify the svg: remove the width and height
and add “preserveAspectRatio="xMinYMin meet" viewBox="0 0 800 960"”
Mobile now works, also increase font size

Managed to change properties inside js. Should display the chart as
whole on mobile but the text is a little bit cut out.

Center charts and chart headings and adjust js properties to make mobile work.
