+
+# Introductie
+
+Deze blogpost en de bijhorende visualisaties zijn gemaakt in functie van het vak Datavisualisatie, gegeven door Bart Mesuere.
+In dit vak kregen we de opdracht om een dataset te kiezen en die te visualizeren. Het was natuurlijk een
+no-brainer om de data die we al een aantal jaar aan het vergaren zijn van Haldis, Tap en Tab te gebruiken.
+
+Als je geïnteresseerd genoeg bent in het lezen van deze blogpost, ben je hoogstwaarschijnlijk geïnformeerd genoeg om te weten
+wat Haldis, Tap en Tab zijn, maar voor de ongeïnitieerden volgt een korte uitleg.
+
+## Haldis
+
+Sinds 2 april 2015 maakt Zeus gebruik van Haldis, een applicatie om het bestellen van eten in groep te vergemakkelijken.
+Dit laat onder andere toe dat mensen die nog op weg zijn naar te kelder toch eten kunnen bestellen. Bekijk
+het project op <https://zeus.ugent.be/haldis>.
+
+## Tap
+
+Tap is onze digitale vervanging van het oude papier-en-streepjes systeem dat we al jaar en dag gebruikten. Elke drankje of
+versnapering was een aantal streepjes waard, wat ons weinig fine-grained controle gaf over de productprijzen.
+
+# Visualisaties
+
+## Haldis
+
+### Afstanden
+
+Op onze eerste visualisatie kunnen we via een timeline zien waar we het vaakst naartoe gaan met Zeus, en welke afstanden
+we bereid zijn om hiervoor te overbruggen. Om de timeslider te gebruiken kan je de timeslider naar beneden of naar boven
+slepen om in of uit te zoomen.
+
+<div id="leafletmap" style="height:500px; width:100%"></div>
+<svg id="slider1" style="width: 100%"></svg>
+<div id="dayButtons" class="has-content-centered">
+  <a class="button is-small is-info is-outlined" data-day-idx='1'>Maandag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='2'>Dinsdag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='3'>Woensdag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='4'>Donderdag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='5'>Vrijdag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='6'>Zaterdag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='0'>Zondag</a>
+  <a class="button is-small is-info is-outlined" data-day-idx='-1'>Reset Filters</a>
+</div>
+<button id="playButton" class="button is-primary">Play</button>
+
+### Punchcard
+
+Op onze tweede visualisatie krijgen we te zien wat de populairste uren zijn voor alle restaurants, zo zien we dat we onder
+andere eens 's avonds laat een frietje durven stekken!
+
+<div class="full-width has-content-centered">
+  <svg id="punchcard" width="1300" height="600"></svg>
+</div>
+<svg id="slider2" style="width: 100%"></svg>
+<button id="playButton2" class="button is-primary">Play</button>
+
+### Instance
+
+In de instance chart van Haldis zien we elke bestelling die
+geplaatst werd, gesorteerd op eerste tijdstip van bestelling.
+
+<div class="full-width has-content-centered">
+  <svg id="instance" width="1200" height="600"></svg>
+</div>
+
+### Rankings
+
+We zien het verloop van de rangschikking van de verschillende restaurants. Interessant om te zien is onder andere de ongeloofelijke stijging van de Fritoloog als onze favoriete frituur.
+
+<div class="full-width has-content-centered" style="overflow-x: auto">
+  <svg id="rankings" width="90%" height="700"></svg>
+</div>
+
+## Haldis & Tap
+
+### Co-occurence van Tap en Haldis
+
+Op de volgende chart zien we welke producten er besteld worden op Tap bij bepaalde restaurants op Haldis. Zo zien we onder
+andere dat er 5% vaker Club Maté besteld wordt bij het Blauw Kotje (frieten) dan bij onze favoriet Ocean
+Garden (chinees)!
+
+<div id="gridlo" class="full-width has-content-centered"></div>
+<button name="updateButton" id="switch" value="Update" class="button is-primary">Switch</button>
+
+### Co-occurence van Haldis, Tap en Zeus events
+
+Hier kunnen we verschillende statistieken van Haldis en Tap met elkaar vergelijken, en tegelijkertijd een eventueel verband
+met de Zeus-events bekijken.
+
+<div class="full-width has-content-centered">
