COVID-19 visualisation & comparative analysis tool v1.0

This tool allows you to observe daily updated COVID-19 data, perform comparative analysis among countries, fit predictive models and more. It accompanies the COVID-19 blog post series to be published in www.libramli.ai/blog. Below you can find an embedded version of the tool or, if you prefer you can directly access it in www.libramli.net

 

What it shows & how to use it

  • Chart area: The coloured dots connected with thin solid curve represents either confirmed cases or fatalities (see Case Type selection options below). The transparent curves correspond to the output of predictive models. The exponential growth model – thin transparent curve, or the logistic growth model, thick transparent curve. For better understanding of how one can use this tool, we refer to our corresponding blog post How to deal with exponential growth bias in COVID-19 pandemic
  • Country selection panel: Either type the country you want to add in the charts or use the dropdown menu to manually select a country.
  • Case Type:  Choose from the drop-down menu whether the graphs are based on number of confirmed COVID-19 infections or on the reported fatalities
  • Exponential Fit: It plots a prediction (thin transparent curves) resulted from fitting the exponential growth model. (See Use data up to this day slider, for options on the range of data that are used in the model). For further discussion see the blog post here
  • Logistic Fit: It plots a prediction (thick transparent curves) resulted from fitting the logistic growth model. (See Use data up to this day slider, for options on the range of data that are used in the model)
  • Time Alignment:  The data of each country are time shifted so as all the countries to have their 100th occurrence (confirmed infection or fatality) aligned, as if they were occurred on the same day. When selected, the horizontal axis of the chart shows days (starting from day 1). When non-selected, then the horizontal axis shows dates. For further discussion see the blog post here
  • Show from (slider): Defines the starting date (or Day if Time Alignment is selected) that is shown in the chart.
  • Show up to (slider): Defines the last date (or Day if Time Alignment is selected) that is shownin the chart. It is allowed to be a future date or day.
  • Use data up to this day: It determins the data that are used for the tuning of the predictive models (exponential growth fit & logistic growth fit). Precisely, the model of each country is optimized using all its data between the first occurrence of a case (confirmed infection or fatality depending on Case Type selection) and the day defined in “Use data up to this day”.

 

FAQs

Can I embed the chart in my website or blog post? Sure, feel free to do so and get in contact ([email protected]) for help. You can embed either the full graph or a snapshot with predefined parameter values such as the following
