I've just merged a couple of old scripts to create a graphical html report from df and to send inline html via sendmail...
Code:
#!/bin/sh

#---create report
(
  echo '<HTML><HEAD><TITLE>STATS</TITLE></HEAD><BODY>'
  echo '<H3>'$(uname -n)'</H3><TABLE BORDER=2 CELLSPACING=0 CELLPADDING=2>'
  echo '<TR><TH>Filesystem</TH><TH>1048576-blocks</TH><TH>Used</TH>'
  echo '<TH>Available</TH><TH>Capacity</TH><TH>Mounted On</TH></TR>'
  df -Pml |awk 'NR>1 && NF==6'|sort|while read FS SIZE USED FREE PERC MOUNT
  do
    PERCENT=${PERC%%%}
    if [[ $PERCENT -gt 90 ]]
    then
         COLOR=red
    else
         COLOR=black
    fi
    echo '<TR><TD>'$FS'</TD><TD ALIGN=RIGHT>'$SIZE'</TD>'
    echo '<TD ALIGN=RIGHT>'$USED'</TD><TD ALIGN=RIGHT>'$FREE'</TD>'
    echo '<TD><TABLE BORDER=0 CELLSPACING=1 CELLPADDING=0><TR>'
    echo '<TD WIDTH='$((2 * $PERCENT))' BGCOLOR="'$COLOR'"></TD>'
    echo '<TD WIDTH='$((2 * (100 - $PERCENT)))' BGCOLOR="gray"></TD>'
    echo '<TD><FONT SIZE=-1 COLOR="'$COLOR'"> '$PERC'</FONT></TD>'
    echo '<TR></TABLE></TD><TD>'$MOUNT'</TD></TR>'
  done
  echo '</TABLE><P>Generated at '$(date '+%H:%M on %d-%b-%y')'</BODY></HTML>'
) > /tmp/df.html

#---email report
export MAILTO="unix@mailinator.com"
export SUBJECT="Report"
export BODY="/tmp/df.html"

 echo "To: $MAILTO"
 echo "Subject: $SUBJECT"

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
