The paper's objective is to carry out a real-time visualization of pandemic sentiment at the very first instance. The paper shows multilevel visualization of sentiment analysis conducted on the covid19 dataset acquired from Twitter. The visualization tools used for real-time data are Google data studio, Python matplotlib, Carto, and Tableau. On Mar 11, 2020, Covid19 was declared a global pandemic, and stage wise lockdown protocols were implemented. The covid19 virus has spread worldwide and consumed millions of people. The impact of the virus is affected not only on the physical body but also on mental health and results in increased distress, depression, anxiety, fear, and panic simultaneously. The data was downloaded using twitter's official API on Mar 11, 2020. Vader sentiment analysis is performed on 3,27,717 tweets downloaded from 200 Megacities globally. The study achieved 50.95% negative and 58.72% positive sentiment and neutral values ranging between 0 to 1 polarity.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
