Mapchart
Purpose & Application
The mapchart is the best chart to display geographic disparities.
This chart is good to compare values of different areas.
📝 For example, the GDP per countries in the world.
The zones can be geographic regions or different areas of a commercial center.
📝 For example, the average basket of the stores of a commercial center.
It can also be used to locate cities or buildings on a map using markers.
In order to create a mapchart, the dataset must include a geographical column (detected automatically by Toucan).
Key features
What makes this graph a killer story?
📌 Markers make it easy to highlight specific points such cities for example and thanks to the color legend, we can see at a glance from which countries they depend.
In our case I can clearly tell that Paris, Lyon and Strasbourg contributes to France GDP 📈
🗺️ Custom base map allows you to display whatever you want! It can be the world, areas, countries, cities, neighborhood and even floor plans of a shopping mall -great to analyze which shops are the most visited and if those shops are located close to each other
In our case I can zoom in Italia and quickly tell how zones are performing. Wooow! 4 areas have a very high GDP : Piemonte, Lombardia, Toscana, Sardegna, Sicilia 🤩
⚙️ Crossfilter functionality allows you to use your map chart as a master with another viz! It can be a horizontal bar chart, a stacked bar one, etc.
🔎 Smooth drill functionality makes it easy on the eye, your user will love it! Add a drill to your mapchart to go in a deeper level of detail.
How easy it is to get the Africa GDP then see the details for each country! 🌍
Compatible and optimized mobile display, get your data anywhere 📱!
