Open Source Data Visualization Tools

Top 15 Open Source Data Visualization Tools

Chartist, Charted, Leaflet, Google Charts, myHeatmap, RAWGraphs and Palladio are some of the top most open source data

Data visualization is the conversion of vast complex data into a pictorial pattern for better clarity and deeper understanding.

Data visualization has the potential of presenting data in much more meaningful ways thereby helping in revealing the minute facts like trends that may otherwise get unnoticed.

Valuenex’s ClusterMapViewer developed a graphic for Google and Nest Labs (Alphabet’s subsidiary) which helped them identify emerging market opportunities.

The graphic basically highlighted clusters of patents filed by various companies that dealt with similar technologies as Google & Nest Labs.

We have already explored various merits and demerits of data visualization tools (You can through go them if you want more insight into this topic).
