I presume you are trying to install that package using sudo dpkg -i package, well, that normally leads to package dependency problems so normally I suggest the use of gdebi. If you have any problematic package remove it. You can check using sudo apt-get check. Now down to business:
sudo apt-get install gdebi-core
With that we have ready gdebi. Now if you use a 64-bit system you may like to install the 64-bit package, likewise with 32-bits.
Now here comes the funny stuff...
sudo gdebi graphviz_2.37.20140208.0545-1\~saucy_amd64.deb

This package is uninstallable
Dependency is not satisfiable: libgd2-noxpm (>= 2.0.36~rc1~dfsg)|libgd2-xpm (>= 2.0.36~rc1~dfsg)
And here is where you stop. The reason is that the stable package depends on package that were dropped of Debian, ergo Ubuntu 13.10:
libgd2 (2.0.36~rc1~dfsg-6.1) unstable; urgency=low
* Non-maintainer upload.
* Support multi-arch: (closes: #652496)
- Mark libgd2-xpm, libgd2-noxpm, libgd2-xpm-dev and libgd2-noxpm-dev
as same.
- Adjust d-shlibs and dh-buildinfo build-dependency.
* Drop .la files.

Those are dependencies of graphviz so they should change them to libgd2-xpm-dev and libgd2-noxpm-dev respectively. If that's the case, you should download the latest build instead 2.38 or later, which includes the correct dependencies.
Whenever u install fresh Ubuntu , you need to update and upgrade the system to install from ubuntu repositories.
sudo apt-get update && sudo apt-get dist-upgrade
Now install anything
sudo apt-get install mysql-server

Why another answer: With anwar's answer you will not get cool update while shubham arawkar's answer is for Ubuntu 16.04 not 16.10(OP's choice). So I'm providing a solution to take care of both the issues.
The Screenlets PPA provides numerous screenlets (desktop widgets), such as RSS readers, weather, clock, countdown, a Conky-like system information widget, folder view, calendars, sensors, and much more.
