Assignment 1a.
- The selected graph is the best option for representing this data
- All numbers double-checked
- Spell check
- Headline/title
- Correct units of measurement
- Description of what the x- and y-axis represent
- Y-axis starts at 0 (if not: Is it clearly shown? Does the editor agree?)
- Conscious choice of colors (explained on request)
- Source
- Instructions for use (if the graph is interactive)
- Context or explanation (if necessary)
- Byline
- Accessibility (contrast, caption for screen readers, attached table, etc.)
- Understandable for someone who sees the visualization for the first time
- The visualization checked on a mobile device

The line chart depicts a changing trend in the number of operational nuclear reactors worldwide from 1954 to 2023. A text annotation and range highlight were used to emphasize the spike from the late 1950s to 1989. Someone who sees the visualization for the first time can instantly grasp the context of the technological competition and nuclear deterrence of the Cold War. Paint & Colour Picker were used to choose from the colours of the cover of Nuclear Power Reactors in the World. 12 data points were labelled, including first & last (too many data points to label all of them).

The column chart depicts a size comparison between the number of reactors, to date, in United States of America, France, China, Russia, United Kingdom (permanent members of the United Nations Security Council). All values or data points are shown. A text annotation was used to emphasize the highest number of reactors in United States of America. Paint & Colour Picker were used to choose from the colours of the cover of Nuclear Power Reactors in the World.
Assignment 1c.
- I crosschecked my data visualizations vis-à-vis the checklist AFTER I had created my charts.
- Colours: Colours can be easily changed, also with RGB & HSV codes.
- Text/labels: Few options to work with text and labels. It is difficult, if even possible, to add description to the x- and y-axis.
- Flexibility: You can duplicate a visualization to start editing a copy.
- Accessibility: Visualizations can be accessed with a link or embed code.
- Smartphone: I had to rotate my iPhone horizontally to view the text annotation inside the chart. Otherwise, no issues.

Assignment 2c.
- I crosschecked my data visualizations vis-à-vis the checklist AFTER I had created my charts.
- Colours: Custom colours can be set.
- Text/labels: Colour, weight, size, outline of text and labels can be set.
- Flexibility: You can add a visualization to a Canva presentation.
- Accessibility: Visualizations can be accessed with a link or embed code.
- Smartphone: I had to rotate my iPhone horizontally to view the text annotation inside the chart. Otherwise, no issues.
Assignment 3.
Datawrapper: I find Datawrapper attractive for beginners. Datawrapper is user-friendly and intuitive to navigate. When you hover over tips/question marks, everything is easy to understand and follow. It is simplicity that serves its purpose, without compromising creativity.
Flourish: It is difficult to scroll up and down the settings/functions. It is not clear what all of the settings/functions do. It would be useful to watch tutorials to get the hang of the full range of possibilities. Flourish offers a much wider choice of charts such as projection map, 3D map, hierarchy, pictogram, Sankey diagram, cards, etc.
My choice: Datawrapper.
