  \frametitle{Introduction to Mayavi}

  \begin{itemize}

  \item Most scientists not interested in details of visualization

  \item Visualization of data files with a nice UI

  \item Interactive visualization of data (think Matlab)

  \item Embedding visualizations in applications

  \item Customization

  \end{itemize}

  \pause

  \begin{block}{The Goal}

      Provide a \alert{flexible} library/app for every one of these needs!

    {Getting hands dirty!}

        \begin{block}{Motivational problem}

        Atmospheric data of temperature over the surface of the earth.

        Let temperature ($T$) vary linearly with height ($z$):

        \begin{center}            

        $T = 288.15 - 6.5z$
