I'm not a New Yorker but I do work in GIS - adding a population stats would give you some good insights. Like that spike in heating complaints - is it just because Manhattan has a denser population? What does # complaints per 10k residents look like?

A raster is probably the best option calculation efficiency wise

Thanks for the feedback. Normalization would certainly be interesting, and you are right that raw counts partly track where people are.

I looked at it, but it easily gets messy: census geographies don't align with the lens approach well, so I would need to assume uniform distribution within each tract, which would be pretty wrong in a city like NYC. And the denominator is not obvious either: residents work for noise, but illegal parking scales with people passing through. So instead of building in my own assumptions, I kept the data side simple and display the raw counts, focusing on the visual concept.

That said, raw counts do hold up for the temporal side: comparing the same area across years should work fine without a denominator, since population changes slowly relative to complaint volumes.

Open to suggestions for a clean approach on the spatial side.

While I agree with an index when looking at larger markets, as comparison analysis, to your point, it's not really valuable when looking at it this closely as the baselines are too unstable.

At a city level The volume of complaints actually is the thing that a decision maker would need to use to optimize where to allocate resources.

What you did here is really really... Beautiful.

Source: NYC 311 Service Requests (2022–2025), NYC OpenData, published by the New York City Office of Technology and Innovation.

Tool: VisQuill GDK for the visualization and lens interaction, Leaflet for the map, OpenFreeMap for the base tiles. VisQuill is a tool I built myself.

What's 311?

[–]vis-benOC: 2[S] 36 Punkte37 Punkte  (0 Kinder)

NYC's non-emergency helpline that you can call or text to report things like noise, illegal parking among others. Every request gets logged and the city publishes the full dataset publicly.

A band that needs to be investigated

Sick. Is VisQuill available everywhere? And how did you get that data into Open FreeMap?

This looks really cool! Impressive build. As a piece of art it's sweet. As data visualization it is not very informative.

I feel like it pretty clearly shows what it's attempting to

[–]TheEsteemedSaboteur [Bewertung versteckt]  (1 Kind)

It does, but it's very difficult to see how the attributes shown distribute spatially, which is arguably the most important piece of information to have about data like this. Some basic spatial statistics would easily allow one to plot heatmaps summarizing hotspots and coldspots for each complaint type, as well as overall rise or reduction in complaints over the target time period, allowing one to read at a glance the geographic distribution of complaints and which neighborhoods should be targeted for priority intervention.

[–]vis-benOC: 2[S] [Bewertung versteckt]  (0 Kinder)

I agree the lens cannot show a citywide pattern at a glance. Worth noting the time dimension though: each arm shows 2022-2025 for that complaint type, so you're reading category, volume and trend together at one location.

A heatmap does one variable at one point in time: showing change across four years for five categories would need either animation or twenty separate maps. The idea here is to invite the user to explore different locations and neighborhoods. So the questions are different: yours is "where is X concentrated", mine is "what's happening here, and is it getting better or worse". A hotspot layer underneath the lens would be the best of both.

I am very tired. I thought it said dumpling. Didn’t even question it.

[–]srawr42 5 Punkte6 Punkte  (0 Kinder)

"Hello, yes, 311? I need to report a severe lack of dumplings in this neighborhood! What is this city coming to?!"

As someone who lives in uptown Manhattan, that spike in heating complaints sounds about right.

Beautiful visualization btw.

I saw this same post last week from a different poster. How can it be OC? Or does OP have multiple accounts?

[–]vis-benOC: 2[S] [Bewertung versteckt]  (0 Kinder)

That was probably my own post from last week, same account. It got removed on a technicality: the required OC comment was caught by the spam filter. So I'm reposting it properly.

Complaining about rats in NYC is like complaining about sand in the desert.

Do Rodents and Noise so we know where the Rat King Rock band is

What the hell is going on at 233rd St to have this many noise complaints, more than anywhere else in the city?

Just wanna say this is super cool

[–]s1ncere [Bewertung versteckt]  (0 Kinder)

why would you call 311 for heating? isnt that a landlord or building issue? what would the city have to do with it?

Add encampment complaints ⛺️

I’ve been 311 reporting a woman who puts out food for stray animals every day for the last two months only for them to tell me nothing is wrong. It’s leading to infestations and they’re doing nothing. 311 is a joke.
