Bar Chart for USA Flights Delay _ React & D3
This interactive bar chart visualizes the average departure delay for USA flights by month. Each horizontal purple bar represents a month, with its length proportionally reflecting the mean delay in minutes. The visualization is built using React and D3.js (with `scaleBand` for the y-axis and `scaleLinear` for the x-axis), rendering as an SVG. Data is loaded from a remote CSV file, pre-processed to calculate monthly averages, and displayed with axis ticks and labels.

This visualization is an analysis about USA flights on-time performance. Each bar represents one month.
Experience :
1> While making this visualization, data pre-processing took me 2 days to get the final result, which is the USA flights delay condition by month. I also got the result by date/day/week and will play it around later.
2> Drawing this bar chart using React & D3 was much more difficult than using vega-lite-api, but it was also more interesting when I created all elements one by one by myself.
One idea I got from these two weeks' assignment was, when I want to realize a visualization in the future, I could use vega-lite-api first to try out all the ideas, and after choosing the best one I can use React & D3 to realize it. However I am not sure if my understand is right or not lol.
