A visualisation of my cycle ride to work in London for #30DayChartChallenge Day22 - mobility (Bermondsey > Old Street).

Took me quite a few attempts to record the data. 😅 Also tried dogs, but there weren't any 😢

Great to see an ever growing network of 20mph roads (green) in London making roads safer. 🤩

Speed is one of the single most important factor in whether a collision takes place and how severely people are injured.

Safer roads also promote #cycling. In the latest NTAS, 55% of people said that safer roads would encourage them to cycle more. Most of them (86%) consider lower speed limits an important aspect of safer roads. (Source: https://www.gov.uk/government/statistics/national-travel-attitudes-study-wave-5/national-travel-attitudes-study-wave-5#cycling)

Maps displaying the road network of London coloured by speed limit between 2016 and 2023. 20mph roads are coloured in green and are expanding over time.

Did you know that you can create stunning tables in Python? 🔢 📊

I used #MakeoverMonday data on Highest Paid Athletes to explore Plottable - an awesome #python library to customise tables. Really like the inbuilt graph options and how easy it is to display images. 🤩

My highlight of the week: Our plumber complimented my hotfix for a water leak saying it's "genius" - I used strings to divert dripping water from a pipe to a container. Not sure it's genius but made my day 😅

After weeks of making #maps for the 30DayMapChallenge, it's time for some #dataviz again.

Looked at what words C-3PO uses most often together (bigram analysis) and visualised them in a network graph (thicker line=more co-occurences). "Oh dear" 😃

Based on Star Wars scripts for episodes 1-6. Made with #python using #nltk, #networkx, and #matplotlib.

#30DayMapChallenge Day29 – Population (and Dot)

Change in population of London 1990-2020 per 1skm. Growth almost everywhere but largest in East London. Unsurprising considering new developments around Stratford (ie. Olympics) and other areas in East since then.

Made in #python #matplotlib, inspired by Jacques Bertin

Found out about this great little tool yesterday.

Perfect Freehand lets you draw smoth, good looking shapes and lines. 🤩 〰️ You can export them to SVG and there is even a #Figma Plugin and #python library!

#30DayMapChallenge Day11 – Retro.

Most common Tube seat pattern (aka moquette) by borough (= largest number of stops on a line in a borough). Some lines share the same patterns.

Which one is your favourite?

A bit of a silly one for today. London borough polygons visualised in a tile grid map of London boroughs.

If you want to know how to make this kind of fishnet grid for any polygon, I’ve documented the process a little bit in this notebook: https://github.com/Lisa-Ho/30-day-map-challenge/blob/main/2022/Day12/london-gridmaps.ipynb

#30DayMapChallenge Day2 – Lines.

Elevation map of the UK and Ireland.

Made with one of my most favourite #python libraries: ridge-map. Super easy to use. You can create stunning visuals with just a few lines of code. Checkout the documenation: https://pypi.org/project/ridge-map/

Wanted to explore elevation data in Yorkshire after a recent visit to Todmorden and hiking along the Pennine Way. Followed this great tutorial https://www.geodose.com/2020/02/how-to-make-beautiful-hillshading-map-qgis.html?m=1 and had a lot of fun playing around with colour palettes, hillshade stylings and contour lines 🤩

Always amazed by what you can do with #QGIS. it's completely free and has a ton of plugins to create almost any map you can imagine.

#NoMowMay prompted me to look into artificial grass & how it's promoted. According to 25 websites selling artificial grass, it's low-maintenance, family friendly & looks great. Some even say it's environmentally friendly because it saves water.

While convenient, artificial lawns actually damage the environment & take away the natural habitat from many species. Not sure #NoMowMay will fix it, but maybe create some awareness.
