How Bangalore Uses the Metro

How Bangalore Uses the Metro

We filed an RTI request with Bangalore's metro authority asking how many people traveled on the metro and got a file with 1.2M rows of data on ridership. Where has the new Yellow Line impacted the city the most? Or what are the most popular metro trips in the city?

AI Research collaborations

A set of data visualizations for a Rest of World story on how countries collaborate for AI research.

Votes in a Name

Votes in a Name

I looked at data from Indian elections to find similar-sounding candidates and analyze some of the different ways they show up. We then tried turning those similarity scores back into visuals which you can play around with. Illustrations by Reechik Banerjee

BLR Water Log

BLR Water Log

Natural drains crisscross Bangalore and are often the places which are the first to flood. We mapped where these are.

Diagram Chasing

Diagram Chasing

I started a data-viz blog with my friend Vivek to explore our many and varied interests, giving us a space to work on them. We have a public ideas page that tracks what we're working on. Published without a strict schedule.

International Math Olympiad

International Math Olympiad

This week's dataset was on every country's scores and medals in the International Math Olympiad. I wanted to visualize both overall medal count and how rankings have fluctuated over the years. The small multiples are actually bump charts! Perhaps a little overwhelming, but I enjoyed using the {patchwork} package.
Shakespeare Dialogue

Shakespeare Dialogue

After a long time away from Tidytuesday, I made a fairly straightforward graphic showing how the 'prominence' of characters changes as the three plays go from Act I to Act V. Represented with a bump chart, the characters are ranked by how much dialogue they have in that particular act and scene.
Journeys of Resilience

Journeys of Resilience

An interactive story on the lives of Ukrainian refugees visualizing data based on comprehensive surveys conducted by the UN International Organization for Migration (IOM). Developed at Revisual Labs with Divya Ribeiro and Surbhi Bhatia.

U.S Polling Places

U.S Polling Places

I mapped addresses of U.S polling places and plotted their locations (probably a population map lol). Geocoding was an interesting challenge; I found out that the Census website provides a nice generous_API. Processed in R but mapped in QGIS (whoops)._A pretty simple visualization for this week, but getting geocoding to work was fun. It took around 4 hours to run through the full dataset in batches of 9999 addresses each.\n
NYT Word Games Dashboard

NYT Word Games Dashboard

My friend and I are hyper-competitive with our NYT word games, this year we want to see who is *actually* better. Using this week's #tidytuesday prompt to create a Shiny dashboard that tracks our daily plays, wins and win margins for the rest of the year. The game is on
Doctor Who

Doctor Who

It's tidytuesday week 48 and we looked at Doctor Who. I made a little nerd postcard from Gallifrey. I think I got the shape pretty close? eh?? Added the unstylized versions at the bottom. Except the title graphic, everything done in R.
R ladies chapters

R ladies chapters

For #tidytuesday week 47, we looked at @RLadiesGlobal chapters, and I probably overdid things. Tbh, I just wanted to use the OpenAI embeddings API to cluster similar chapters but one thing led to another and well yeah, I made a dashboard. You can search by topic or locations. All the processing for the data was done in R and the website is (obviously) built with Sveltekit. I used the OpenAI APIs to extract keywords for tagging and to 'recommend' chapters based on the kind of events they host. It cost me ~$0.90.
Diwali sales

Diwali sales

For #Tidytuesday week 46, I used weighted log odds to see what kind of products are potentially more 'popular' during Diwali season. Made in r + Figma
U.S elections

U.S elections

For tidytuesday week 45, I accepted that the US election system is beyond my understanding lol. Made a couple of things, but settled on trying to recreate an old @FiveThirtyEight analysis and graphic.
Taylor Swift

Taylor Swift

I analyzed repetition of lyrics in Taylor Swift songs. If you take away similar phrases and words from the 1989 album, how many songs can be reduced by at least 60%? All of them! The repetitions make them catchy as heck.
