I'm a professor of mathematics at the University of North Carolina Asheville. I've also done a fair amount of consulting work over the years focusing on scientific and data visualization.
I'm happy to be part of the first Observable Ambassador's cohort.

coviddata = {
let data = await FileAttachment("CovidData.csv").csv({ typed: true });
data.forEach((o) => (o.Date = d3.utcParse("%m/%d/%Y")(o.Date)));
data.max_cases = d3.max(data.map((o) => o.cases));
data.max_deaths = d3.max(data.map((o) => o.deaths));
return data;
}
// There are only four dates to consider
_.uniq(coviddata.map((o) => o.Date))
Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
