In der Java-Welt begegnet man früher oder später sogenannten Maps (der Map-Schnittstelle) – und das völlig zu Recht! Sie ist ein grundlegender Bestandteil der Java Collection Frameworks und ermöglicht es, anders als Listen, Daten als Schlüssel-Wert-Paare zu speichern.

Что не так с cProfile в Python

Некоторое время назад с коллегой обсуждали вопрос профилирования программ на Python. Он сказал, что использует gprof2dot для пост‑обработки данных cProfile , в ответ я высказал мысль, о том, что было бы хорошо использовать более современные средства профилирования. И задумался, а можно ли какие‑то из существующих инструментов приспособить для работы с данными в формате pstat , но которые более удобные и дают больше возможностей для анализа.

@ringwoodunitarians I think you are talking about a "treemap".

I imagine that many programs can produce them, but some examples would be
Power BI: https://learn.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-treemaps?tabs=powerbi-desktop
Excel: https://support.microsoft.com/en-us/office/create-a-treemap-chart-in-office-dfe86d28-a610-4ef5-9b30-362d5c624b68

Most of the time I'm really quite fond of Hackney Council. Their Parks and Green Spaces department have just answered a long-felt want of mine.

"This map displays data from the Council's tree management software and currently identifies in excess of 45,000 trees plotted across streets, parks, housing and open spaces. The map does not represent trees on private land, unless they are protected by a Tree Preservation Order (TPO)."

I removed the dates from URLs in this case (YYYY/MM/DD) to get a better overview. Note that you can include links* in the chart:

Since I was already making these figures, might as well submit them for the #30DayChartChallenge Day6: #OWID.

CO2 emissions by regions and countries. Made in #Stata using the #treemap package (https://github.com/asjadnaqvi/stata-treemap). One of the hardest ones to code but it's pretty solid now.

Several @Stata packages updated. Install from #GitHub. Up soon on #SSC.

#treemap v1.41 now correctly collapses categories based on the threshold value. More options added.

https://github.com/asjadnaqvi/stata-treemap

A major update to the @Stata #treemap package is now out. v1.4 fixes has the following major changes:
- The layer order is now higher to lower tiers
- "percent" option renamed to "share"
- Children now respect the boundaries of the parents.

More 👇

Here are data tests using #COMTRADE. The #treemap shows the % share of petroleum exports by country and subregion.

#sankey shows subregion to subregion flows of petroleum products.

Both packages are part of the #heirarchical #dataviz series. More on this later.

Btw #treemap was 10x more complex to program than #sankey. It employs a divide-&-conquer algorithm that attempts to optimize box placement, either by slicing or dicing, for a given width, height, aspect ratio. This means that a change in dimensions = complete change in layout.

#treemap v1.3 of the @Stata package is now up on #GitHub. I used it the last few days and found some bugs + features missing. The updates are:

- fixes to formatting
- added a "percent" option to show percentages
- add options to control label gaps

A slightly different use of a #treemap: For "Klartext", the magazine of the German School of Journalism with the topic "Land", the students assigned a specific size to each story. In the table of contents, we were thus able to show how these areas together make up a page, just as the stories make up the magazine.

MSc Assignment 2 - Data Analytics Principles

I'm doing an apprenticeship MSc in Digital Technology. In the spirit of openness, I'm blogging my research and my assignments.

This is my paper from the Data Analytics module. I enjoyed it far more than the previous module.

This was my second assignment, and I was amazed to score 72%. In the English system 50% is a pass, 60% is a
