    <p>If you use SVG, you can easily create the shapes with a function like:</p> <pre><code>/** * @param {SVGPathElement} aShape a SVG path element * @param {number} radius the radius of the plectrum's arc * @param {string} fillColor color in "#rrggbb" format */ function drawPlectrum(aShape, radius, fillColor) { // Creating a string which defines a path in SVG // M = moveto, A = line to, etc. See http://www.w3.org/TR/SVG/paths.html var ss="M "+parseInt(0)+" "+parseInt(0)+" "; // moveto 0, 0 ss+="L "+parseInt(0)+" "+parseInt(radius)+" "; // lineto 0, R ss+="A "+parseInt(radius)+" "+parseInt(radius)+" 0 0 0 "+parseInt(radius)+" "+parseInt(2*radius)+" ";// elliptic curve to R, 2*R ss+="A "+parseInt(radius)+" "+parseInt(radius)+" 0 0 0 "+parseInt(2*radius)+" "+parseInt(radius)+" ";// elliptic curve to 2*R, R ss+="A "+parseInt(radius)+" "+parseInt(radius)+" 0 0 0 "+parseInt(radius)+" "+parseInt(0)+" "; // elliptic curve to R, 0 ss+="Z"; // closepath // The d attribute of the path element holds the line information // In XML the element will essentially be &lt;path d="*the created string*"&gt; aShape.setAttribute("d", ss); // Give the color aShape.setAttribute("fill", fillColor); } </code></pre> <p>Successive drawings looks something like this:</p> <pre><code> // Note that 3 different path elements are used to overlap the plectrums drawPlectrum(node, 100, "#aaaaaa"); drawPlectrum(node2, 75, "#33dd33"); drawPlectrum(node3, 50, "#3333dd"); </code></pre> <p><strong>Edit 1:</strong> Added more comments in the code for better understandibility</p> <p><img src="https://i.stack.imgur.com/6L3W3.gif" alt="plectrum"></p>

    2. COThis seems to be java code, `parseInt` @tinkerbeast can you please elaborate. Also if you can draw the way you showed, can you tell how SVG is involved ? I am curious

    3. COSVG is an XML format to describe vector images. In my example I'm just creating a Path element (http://www.w3.org/TR/SVG/paths.html or easier http://www.w3schools.com/svg/svg_path.asp). The code is actually JavaScript code. I assumed a web-solution.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
