Data and YouTube Video

The purpose of this visualization is to provide information about the different types of flu cases recorded from the CDC flu reports. It is meant for the general public and medical officials to gain information about the flu. This is achieved in the form of two pie charts, a line chart, and a stacked bar chart.

The data is showing the amounts of positive flu cases across the US. This visualization allows you to do multiple filtering tasks:

You can filter which years are shown by using the season dropdown menu. You can look at data from 1997 to 2021. Also, for the more recent years, you can look at data from public health and clinical labs separately. You can also take a look at separate states rather than the whole US.

For the visualizations themselves, in the pie charts you can take a look at the cumulative data from a specific season or just the most recent 3 weeks from that season. The line and stacked bar charts both have checkboxes which allow you to filter out which lines are shown.

Regarding viral surveillance, the data was collected from World Health Organization and National Respiratory and Enteric Virus Surveillance labs, and public health labs and clinical labs report the data through either of these organizations. All of this data gets reported to the CDC. For outpatient illness cases, the data was collected through the US Outpatient Influenza-Like Illness Surveillance Network. This network consists of many outpatient healthcare providers across the US, and these healthcare providers also report their data to the CDC.

Here is a YouTube video of me giving a quick demo and critique of this visualization: https://youtu.be/kY4FxqCO0Ew
