There are people who look at a spreadsheet and see the magic. There are others who look at a spreadsheet and their eyes go all blurry and there's a strong urge to take a nap. No judgement on either type, but sometimes you need to make it easier to digest.
Putting rows and columns of data into a format the helps people understand "what it's all about" is usually called data visualization. There a lots of tools out there to create charts and graphics from spreadsheets - including ones built in to Excel or Google Sheets. Sometimes you need something more robust though - and the best tool for the job is D3.
Case in point: dojo4 recently finished a job for 350.org - an organization focused on reducing fossil fuels and moving to 100% renewable energy sources. We used the concept of a chord diagram to represent the efforts of several groups and organizations targeting international banks that fund fossil fuel projects around the world. The color coding gives a quick overview on the groups and their particular fossil fuel focus.
Users can hover over an organization and see which banks they are targeting:
Or hover over a bank and see which groups are targeting that specific bank.
(note that the names of banks and organizations have been removed for privacy)
I enjoyed working with dojo4. The team really wanted to understand how a visualization of my data would be valuable and they seem to work from there. I now have an accessible and engaging graphic that tells a story of where there are gaps, redundancies, and opportunities for more coordination. I appreciated how they took the time to learn my organization's aesthetics and worked to match our style. –Senior Global Analyst, 350.org
