The challenge was my first approximation to DLQIs, psoriasis indications, and statistical graphs in the pharma industry in general. My favorite entry was made by my colleague Paolo Eusebi, who sent a [slope chart](https://vis-sig.github.io/blog/posts/2021-02-07-wonderful-wednesdays-february-2021/) comparing the effects in Placebo and Active treatments. The March 2022 challenge was about selecting our favorite entry from all the participations that the Wonderful Wednesdays have had in the last two years. And, if possible, try to improve it. Using Paolo's idea I tried to strengthen the comparison between both treatments: instead of using opacity for describing the flow of patients, I used the stroke width of the lines. I also tried to be more descriptive around the items of DLQI. For those unfamiliar with the term, DLQI (Dermatology Life Quality Index) is a method to measure the quality of life for patients with different skin conditions, such as psoriasis ---- Data from February 2021's [Wonderful Wednesdays' Challenge](https://github.com/VIS-SIG/Wonderful-Wednesdays/tree/master/data/2021/2021-01-13): - Show the multidimensional nature of DLQI with any analytical tool and translate the results in an effective visualization - Show the effect of the treatment, possibly reflecting the multidimensional nature of DLQI 34:T682,function createPlot(dots, lines) { const new_dots = dots.slice(0); const new_lines = lines.slice(0); new_dots.forEach((d) => (d.type = "dots")); new_lines.forEach((d) => (d.type = "links")); const this_data = new_dots.concat(new_lines); const title = metadata.filter((d) => d.item === this_data[0].dlqi_item); return Plot.plot({ height: width < 600 ? width * 0.6 : (width * 8) / 16 / 3, width: width < 600 ? width : width / 3, style: { backgroundColor: colors.black, color: "white" }, color: { range: [colors.drug_a, colors.drug_b] }, x: { domain: ["Baseline", "Week 16"], tickFormat: (d) => (d === "Baseline" ?
