Did you add the dll or did you add a 'reference' to the assembly?

check your web.config file
under system.webserver>handlers add or check if exists

HTML

<remove name="ChartImageHandler" />
      <add name="ChartImageHandler" precondition="integratedMode" verb="GET,HEAD,POST">
        path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    </add>

also under appSettings

HTML

<add key="ChartImageHandler" value="storage=Memory;timeout=30;" />

and under pages>Controls

HTML

<add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting"
          assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

finally in system.web>httpHandlers

HTML

<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
        validate="false" /></add>
