ASSIGNMENT 1: DATAWRAPPER

EXERCISE: A

Choices made: For this chart, I chose a dark red color for the line to draw immediate attention and emphasize the trend in the number of nuclear reactors worldwide from 1954 to 2023. To make the chart more informative and user-friendly, I highlighted 2018—the year with the highest number of reactors—with a vertical annotation, ensuring the peak is clearly visible and easy to understand. A concise description was added to provide direct context about the data and its significance. Lastly, the title was crafted to clearly communicate the purpose of the chart, making it easy for viewers to grasp what the visualization represents at a glance.

Exercise : B

Choices made: The countries were put on the 'x axis' and the number of reactors they produced on the ý axis' to help the viewers in having a clear vision of the column chart as the aim was to demonstrate the top 10 countries with the highest number of reactors. A short description regarding the countries with the highest and lowest number of reactors among the top 10 was also put to make it easier for the viewer to interpret the data.

EXERCISE : C

• Have you followed the checklist for visualizations (every step)? - yes
• Colours: How easy or difficult is changing colours using the tool? - quite easy not so difficult

• Accessibility: What are the different accessibility options provided by the tools? -The column chart includes accessibility options such as alternative text for screen readers, which describes the top 10 countries with the highest number of nuclear reactors. The chart uses clear, legible font sizes, and tooltips are enabled for detailed information on each data point.
• Smartphone: How do the charts appear on your smartphone? Have you faced any issues while accessing them?- they appear the same,no i did not face any issues

ASSIGNMENT 2: FLOURISH

EXERCISE:A

Choices made: The title and subtile was added to keep the chart direct and straightforward for the readers. The years were put on x axis and the number of reactors on the y axis. The color red was chosen to bring attention to the chart and make the interpretation of data easy.

EXERCISE:B

Choices made: The names on the x and the y axis was put to make the data interpretation easy for the readers. The title and subtitle was also added to the bar chart to signify the top 10 contributing countries for the nuclear reactors with USA being the top most country and UK being the last among these 10. The color black was chosen to make it seem like a close relation to nuclear reactors.

EXERCISE:C

• Have you followed the checklist for visualizations (every step)?- Yes absolutely
• Colours: How easy or difficult is changing colours using the tool?- It was easy as it was in front under different headings on the right side
• Text/Labels: How easy or difficult is it to work with text and labels in the tool?- very easy

• Smartphone: How do the charts appear on your smartphone? Have you faced any issues while accessing them? - they appear correct and no did not face any issues

ASSIGNMENT 3 : COMPARISON

• In what context do you think Datawrapper is the best tool, and why? When would you not use it?I think Datawrapper excels in creating static and responsive charts for embedding into articles and reports. Its simplicity and focus on accuracy make it ideal for newsrooms or academic papers. It's perfect for charts that prioritize clarity and accessibility, such as bar charts, line charts,etc.I think I would not use it for highly customized designs or animations.
