Data visualization used in the Chai Jing: under the Dome

In recent days Chai Jing "Under the Dome" broadcast volume has broken billion, the author looked also very touched. There are a lot of visual graphs in this video, this article summarizes this.

My throat is more sensitive, as long as the air quality is not good, take a breath to feel the throat itch. Therefore, I pay more attention to air quality than the average person. I always pay attention to the domestic air quality index:

I feel very happy when I see a few green spots occasionally.

Chai Jing at the expense of millions, with easy-to-understand language, video, slide to introduce the dangers of haze, and put forward a lot of suggestions, let me deeply moved. One of the words I was very impressed is that when it comes to parents who want to let their children get used to the fog, an American expert said, it means:

Some people stay in the haze for a long time, the feeling of physical discomfort seems a lot better, it is not to produce immunity, but his body lost this function.

There really are people around me. Every time I mention air quality, I find a lot of people do not care about it, the main reason is that their body does not appear symptoms. For example, someone lives in Shanxi, I just talk about the air quality of the topic (not out of malice), they immediately with the point of explosives to explode, said "environment is good, life is very comfortable".

Love my hometown, anyone is so, I can understand. I am not meant to belittle my hometown, but to speak of a social problem. They are "not surprised" and may indeed have their advantages. However, if the "air is a problem" is not recognized, the problem will never be resolved.

I am also the first to know 12369 This number, in the future to try to meet the situation, can solve the problem is still in the second, at least let people know that there is concern in the community. I hope we can all act and start from ourselves.

On this video, the online rhetoric seems to be divided into two factions, arguing with each other, there are many personal attacks of speech. I do not comment on this. However, I see a paragraph on the Phoenix, I feel very reasonable, special record here, but also hope to share to you:

Czech statesman Javier Havel devoted his life to the creation of civil society, and in 1989, established a code of dialogue for the Civic Forum in Prague:

1. The purpose of dialogue is to seek truth, not to compete.
2. Do not make personal attacks.
3. Keep the theme.
4. Use evidence when debating.
5. Don't stick to your mistakes and not change them.
6. Distinguish between dialogue and speech alone.
7. The dialogue has to be recorded.
8. Try to understand each other.

Well, in the "Dome", there are a lot of visualization techniques.

1. Column Chart

2. Line chart

3. Pie chart

4. Map-related

column, line, scatter, which can be called a simple chart.

Pie charts, force guides, tree charts, string graphs, etc., can be called complex charts. Pie charts are the simplest of complex charts.

From a D3 point of view, a simple chart does not use layouts, and complex charts are used.

A simple chart with the most use of video, in fact, data visualization has a point: for a set of data, can be used simple chart, without complex charts, not the more complex the better the chart. Simple charts are the easiest for most people to understand.

Thank you for reading.
