Data visualization example (1): Data visualization strategies have been utilized over two centuries. Lecture pod 3 first discusses a data visualization that depicts the failure of Napoleon’s invasion into Moscow which occurred in 1812.
A French engineer created this map, 50 years after the failure of Napoleon’s invasion into Moscow which occurred in 1812. This diagram displays several different variables.
The thickness of the line indicates the strength of the army at critical points. From left to right is the army crossing the river, with 422,000 and arriving in Moscow with only 100,000 men. From right to left (the darker line) shows the army returning to the west. Only 10,000 men survived. The vertical lines connect the temperature to the location.
Data visualization example (2): The second data visualization that lecture pod 3 discusses is one that was created by Florence Nightingale who played a significant role in the Crimean War (1858). The Crimean war was between the Russians and alliance with the ottoman empire and the British. Florence nightingale also helped to care for wounded soldiers.
The graph demonstrates that soldiers died from diseases more than wounds in battle. It goes around in a circus for a full year then crosses to the second year (left to right).
Nightingale wasn’t just famous for being a nurse, she was also the first female statistician. She was a significant part in developing proper sanitation for wounded soldiers and helped solve malnutrition among them. The graph below demonstrates how the death toll of soldiers decreased over a period of time due to Nightingale’s effective attempt to prevent disease and malnutrition by providing proper sanitation and adequate nutrition.
Although her charts were not be perfect but they were a huge innovation in her time.
Data visualization example (3): The third example that lecture pod 3 discusses is the work of Otto Neurath (1882 – 1945). He was a pioneer for socialism. He started a museum where he aimed to make social and economic relationships understandable, especially for the uneducated.
He developed a system known as the ‘international system for infographic picture information.’
Neurath also introduced exhibition packs that were made for the general people, as Otto believed that museums should be brought to the people, not the other way around. These were shipped all over the country and put on display at all sorts of venues to widen ideas. The precedent below displays a photograph of Neurath cutting out pieces to create an exhibition pack to distribute to the masses.
Viewing lecture pod 3 has allowed me to gain an appreciation of how one of the most significant strengths of data visualization is that it can reduce the time to understand a certain event. Attempting to analyse paragraphs of texts, facts, theory and trying to make sense of it can be quite tedious and I have found that data visualization has augmented my capacity to absorb the data efficiently.
Another aspect of this lecture that I found intriguing was how Neurath created educational visualizations that could be communicated effectively towards the masses, including the uneducated. As education was a luxury during early 1900’s, I admire that Neurath acknowledged this and put in considerable effort to ensure his message reached the masses through an easy-to-understand method.
Lecture pod 3 has allowed to me to gain an understanding of the ways that data visualization was historically used and how effective it has helped us interpret data in a unique way that allows us to identify trends, patterns and correlations to advance our understanding of the world.
