\asciimode can be overkill because it makes also “%” a normal character, better you define a command which change the catcodes.

\def\googlechart
  {\begingroup
   \setcatcodetable\vrbcatcodes
   \dodoubleempty\dogooglechart}

\def\dogooglechart[#1][#2]%
  {\endgroup
   \externalfigure[#1][method=png,#2]}

\starttext
\googlechart[https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World]
\stoptext
