 Of all tools for data visualization, I mostly enjoy working with Vega-Lite. As I enhance my skills in making the visualizations using it, I become increasingly interesting not just in the "dataviz" part of its capabilities, but also on making it aesthetically compelling, as well as challenging myself to reach the limits of what is possible with Vega-Lite. I am by no means near the limits so far, however I got increasingly interested in replicating the charts I see throughout the internet.

 One that caught me attention is Tableau's Viz of the Day: [Seven Bar Charts to Visualise Year-Over-Year Growth](https://public.tableau.com/app/profile/jacob.rothemund/viz/SevenBarChartstoVisualiseYear-Over-YearGrowth/Dashboard)

 - `text` mark with calculated `text_label`
 - two separate `point` mark layers, each with a different color but more importantly - `triangle-up` and `triangle-down`. We cannot encode the two marks dynamically (or, rather, we cannot make dynamic fill color which is my goal here) so we'll need to do it separately for positive and negative changes.

-В першу чергу я зупинився на генераторах статичних сайтів, з міркувань простоти.

-З-поміж багатьох існуючих фреймворків обрав один з найбільш популярних (бо по ньому має бути багато напрацювань спільноти) та не закинутий опенсорс проєкт.

-Замість ручного додавання скриптів та ембеддингу як в [туторіалі](https://vega.github.io/vega-lite/usage/embed.html), є можливість підійти трохи гнучкіше і завантажувати vega-lite бібліотеки лише на тих сторінках на яких вони потрібні, а також параметризувати деякі із штук за замовчуванням:
-
-
-```html
-<!-- Create a unique ID for the div where the Vega-Lite visualization will be rendered -->
-<div class="vegaVis" id="{{ .Get "id" | default "vega-lite-vis" }}"></div>
-<script>
-  const spec = {{ .Inner | safeJS }};
-  spec['width'] =  spec['width']? spec['width'] : {{ .Get "width" | default 700}};
-  spec['height'] = spec['height']? spec['height'] : {{ .Get "height" | default 300}};
-  vegaEmbed('#{{ .Get "id" | default "vega-lite-vis" }}', spec, {"actions": false}).catch(console.error);
-
-</script>
