Hi Friends -
Onwards to this week's links...
Welcome to issue 100 of the DashingD3js.com Weekly Newsletter
- On The Political Economy Of The GeoJSON Format
During the first ever #mapTimeLEX—an event inspired by @alyssapwright, and here in Lexington, largely an ode to @lyzidiamond and @mappingmashups—Dr. X graciously posed the question that the rest of us were too afraid to ask: “What is the political economy of the GeoJSON format?”...
- How To Create Live Updating And Flexible D3 Line Charts Using Pseudo-Data
One of the bigger challenges in visualizing data is making your charts responsive so that they can resize no matter what range of data is thrown at it. Things get even more complicated when the dataset is actually a collection of many individual sets of data. One obvious example of this is a dataset containing (x,y) coordinates for multiple lines. The goal is to create a chart similar to the one below, which adapts to any new data thrown at it...

- Found: The Manhattan Apartment That’s The Farthest From Any Subway
...In the spirit of my earlier Starbucks-Distance analysis, I turned to Open Data to answer [this] question once and for all. To do so, I merged two data sets, the MTA Subway Station Entrance data set and PLUTO, which gives information on all lots in NYC. I then calculated the distance from the center of each lot to the nearest station.The map of lots colored by distance from subway entrances looks like this (with green being close and red being far):...
Neatline is a geotemporal exhibit-builder that allows you to create beautiful, complex maps, image annotations, and narrative sequences from Omeka collections of archives and artifacts, and to connect your maps and narratives with timelines that are more-than-usually sensitive to ambiguity and nuance.
- Introducing Mapbox GL
We just released Mapbox GL — a new framework for live, responsive maps in every iOS app. Now developers can have the most detailed maps sourced from ever-updating OpenStreetMap data, as well as the ability to fully control the style and brand to design maps that perfectly match their app...
- Using Google Polymer And Force.com To Draw Charts
We have been experimenting on developing Google Polymer Components that works smoothly with force.com platform and use charts to display data on visualforce. The idea is to develop robust, scalable reusable components which are easy to embed on visualforce pages...
D3.js Reading and Videos
- Intro To D3.js - Square, Inc.
In Square’s new engineer onboarding program, which we call NEO, we offer short courses and lectures on a variety of tools that we use at Square. We started to collect notes from our course on D3.js and found the notes were well-suited for a tutorial — and worth sharing...
- Introduction To Graphing With D3.js
This presentation is a series of demonstrations showing the process for building a D3.js scatter plot. It is intended to be run locally with the index.html file open along-side the browser window. The code can be cloned or downloaded from github. Instructions for starting a server are shown in the project README.md. Download the talk notes - contains a list of the operators (with summary definitions) that were used...
- Minard + Napoleon + Neatline
...Military history is often about how things change over time on maps, which is basically the tag line for Neatline. In fact, I’ve always assumed that military history played a pretty big role in inventing the whole vocabulary of visual concepts and techniques that have been picked up by digital tools like Neatline – the flowcharts, the arrows, the diagrammatic ways of representing how things move from one place to another.
- Visualizing MNIST: An Exploration Of Dimensionality Reduction
At some fundamental level, no one understands machine learning...My hope is that, through visualization and observing more directly what is actually happening, we can understand neural networks in a much deeper and more direct way. And so, the first thing on our agenda is to familiarize ourselves with dimensionality reduction. To do that, we’re going to need a dataset to test these techniques on...
- Game Of Nobels: The Top 10
Some countries, such as the U.S., dominate the prize charts overall, but fall curiously short when it comes to literature. France has the most literature Nobels (Patrick Modiano, a French author, won the prize this year), while Russia has a strong showing in Physics. Tap the countries or categories to see the connection between them...
Hope that you had a great past week and that next week is even better!
Wishing you the best,
