Information Visualization technics has been widely used in exploring complex data space. In the area of network visualization, the extreme complexity and professional requirements of IT engineers make it hard to design visualization strategies facilitating their daily works. This paper introduces an interactive visualization tool kit for managing network systems. It starts with the research of different visualization technics and existing visualization systems, follows with the concept development process, including user research and the evolution of mockups. A final prototype is proposed, evaluated by discussion with users.
