Mike Bostock, a key developer of D3.js and co-creator of ObservableHQ, created a diagram that visualizes character co-occurrences in Victor Hugo’s Les Misérables. What strikes me about this diagram is how a story traditionally told through novel, musical, and film can collapse into a single, atemporal matrix. This is what it looks like:
Bostock notes the following about using an adjacency matrix over a traditional node-link diagram when visualizing complex networks:
A network can be represented by an adjacency matrix, where each cell ij represents an edge from vertex i to vertex j. …
In an article posted in July 2020, I wrote about VC-backed company valuations and how they’ve evolved over the last 20 years. Specifically, I looked at the top 15 highest valued startups around the world — what I unimaginatively call “winners” — and how their relative quarterly valuations changed from 2000 to 2020. Some of the observations I made in the article were obvious, namely, winners are getting bigger and emerging globally. Other observations weren’t so obvious: the gap between big winners and really big winners is widening, valuations of winners reacted differently to the 2000, 2008, and 2020 macroeconomic…
The following animation tracks the top 15 highest valued VC-backed companies over the last 20 years. Quarterly valuation changes from up rounds and down rounds creates a race-like shuffling between companies. Companies that exit (IPO, M&A, OOB) are automatically removed from the chart.
Distilling 2 decades of valuation data into a 2-minute animation shed light on the following trends:
