By using E2D3 (Excel to D3), you can create dynamic and interactive graphs on Excel without programming, because E2D3 bridges a gap between a statistical tool Excel and a graphical tool D3.js. So E2D3 improves organizational or individual productivity to create a data visualization product as an output of data analysis. Main targets of E2D3 are data-journalists who need to increase a visual impression of web based news, business persons belonging to a department of Sales and Marketing, and students and teachers in social and science classes. E2D3 is the first open source Office app project in the world. E2D3 have provided many middle-ware functions by which programmers can easily connect not only D3 but also every JavaScript graphic library and Excel sheets. Moreover, E2D3 have built up a Github-linked-Office app platform in which the programmers easily share their own graphs to the world. Therefore, E2D3 have successfully integrated several type engineers into Office platforms and leveraged the power and context of the Office platforms. Please see our website, http://e2d3.org/ !
